Development of a tailor-made bis(oxazolidine)pyridine-metal catalyst for the [3+2] cycloaddition of azomethine imines with propiolates

A series of bis(oxazolidine)pyridine ligands (the PyBodines) were newly designed and synthesized for the development of a highly efficient, tailor-made catalyst for the [3+2] cycloaddition of azomethine imines with propiolates. The PyBodine(L-Ala)-Cu(OAc)(2) catalyst was selected on the basis of solid-phase catalysis/CD-HTS and exhibited high efficiency, producing the (R)-adducts with excellent enantioselectivity.

Lanthanide Complexes with a Tripodal Nitroxyl Radical Showing Strong Magnetic Coupling

A series of isomorphous mononuclear complexes of Ln(III) ions comprising one stable tripodal oxazolidine nitroxyl radical were obtained in acetonitrile media starting from nitrates. The compounds, [LnRad(NO3)(3)] (Ln = Gd, Tb, Dy, Tm, Y; Rad = 4,4-dimethyl-2,2-bis(pyridin-2-yl)-1,3-oxazolidine-3-oxyl), have a molecular structure. Their coordination polyhedron, LnO(7)N(2), can be described as a tricapped trigonal prism with symmetry not far from D-3h. The extracted value of 23 cm(-1) for the antiferromagnetic coupling of Gd-Rad established from the DC magnetic and EPR data is a record strength for the complexes of 4f elements with nitroxyl radicals. The terbium derivative displays frequency-dependent out-of-phase signals in zero field, indicating single-molecule magnetic behavior. With an applied field of 0.1 T, an effective barrier of 57 cm(-1) is found.

Polynuclear Complexes of Ligands Containing in Situ Formed Oxazinane and Oxazolidine Rings with Appended Alkoxyl and Phenol Groups

In situ formation of ligands is an efficient approach to synthesizing novel complexes with unique coordinating moieties. Oxazolidines and oxazinanes are 1,3-N,O-containing five-membered and six-membered heterocycles, respectively. Metal complexes of Ligands derived from these two heterocycles are rather rare. In this work, we designed and synthesized a novel multihydoxy ligand, 2((2,3-dihydroxypropylamino)methyl)phenol (H3L1). It contains both aminoethanol and aminopropanol units, which may be employed to react with aldehydes to afford oxazolidines and oxazinanes, respectively. Thus, H3L1 was reacted with metal salts in the absence cr presence of aldehydes to afford complexes [Cu(HL1)](2) (1), [CuL2](4)center dot 4CH(3)OH (2) [Zn5Na2(L-3)(4)(DMSO)(2.65)(DMF)(1.35)]-DMF (3), and [Ni(HL4)](2) (4). Complex 1 is a dialkoxo-bridged binuclear Cu(II) complex. The coordination moieties are linked by intermolecular C-H center dot center dot center dot O hydrogen bonds to afford a 1D double-chain supramolecular structure. Interestingly, in complexes 2-4, H3L1 has been reacted with formaldehyde, salicylaldehyde, and 2,6-diformyl-4-cresol to afford novel ligands H2L2, H3L3, and H3L4, respectively. The combination of in situ formed oxazinane or oxazolidine rings with appended alkoxyl and phenol functionalities in these ligands has been demonstrated to form a rich diversity of coordination structures. Thus, 2 is a tetranuclear Cu(II) complex with a face-sharing double defective cubane core structure. In this complex, (L-2)(2-) ligands coordinate in two different bridging modes with the Harris notations of 3.1(1)2(12)2(13)1(1) and 3.1(1)3(123)1(1)1(1), respectively. Complex 3 has an interesting heptanuclear Zn5Na2 core structure. A central Zn(II) is coordinated with four alkoxo O atoms from four (L-3)(3-) ligands. Each of the O atom further bridges another Zn(II) atom, resulting in a Zn-5 moiety, which is then connected to two Na+ by phenoxo O bridges, finally affording the Zn5Na2 core. The bridging mode of (L-3)(3-) can be designated as 4.2(12)2(13)1(1)3(124)1(1). And Complex 4 is a binuclear Ni(II) complex containing di-mu(2)-phenoxo bridges. The coordination moieties are linked by intermolecular C-H center dot center dot center dot pi, C-H center dot center dot center dot O, and pi center dot center dot center dot pi interactions to afford a two-dimensional supramolecular network. These results indicate that the combination of in situ formed oxazinane and oxazolidine rings with appended phenol and alkoxyl functionalities is an efficient approach to developing novel ligands and complexes with a rich structural diversity. Variable temperature magnetic data measurements revealed that medium antiferromagnetic interaction exists between the Cu(II) centers in complex 1 with a -2J value of 278 cm(-1). And in complex 4, weak antiferromagnetic coupling occurs between the Ni(II) centers, with a -2J value of 9.36 cm(-1).

Catalyst-Free Stereocontrolled Formal [3+2]-Cycloaddition of CO2 for the Synthesis of Enantiopure Spiro[indoline-3,5 ‘-oxazolidine]-2,2 ‘-diones under Aqueous and Ambient Conditions

A highly efficient regio- and stereoselective spontaneous formal [3 + 2]-cycloaddition of CO2 in aqueous medium is developed for the one-pot synthesis of spiro[indoline-3,5′-oxazolidine]-2,2’-diones with excellent enantiopuirity (ee up to 99%) under catalyst-free and ambient conditions. The detailed study reveals NH-spiroaziridine- and 3-(aminomethyl)-3-chloro-oxindoles, two in situ generated reactive intermediate compounds for the spontaneous cycloaddition with CO2, and the latter is responsible for the stereoselectivity. An unprecedented mechanism of desulfinylation is also disclosed herewith.

Biomimetic synthesis, antibacterial activity and structure-activity properties of the pyroglutamate core of oxazolomycin

Biomimetic intramolecular aldol reactions on oxazolidine templates derived from serine may be used to generate densely functionalised pyroglutamates, which are simpler mimics of the right hand side of oxazolomycin. Some of the compounds from this sequence exhibit in vivo activity against S. aureus and E. coli, suggesting that pyroglutamate scaffolds may be useful templates for the development of novel antibacterials, and cheminformatic analysis has been used to provide some structure-activity data.

Stereochemical control on the Michael addition of chiral 1,3-oxazolidine-2-thiones to N-crotonyl 1,3-oxazolidin-2-ones

Addition of both antipodes of 4-phenyl 1,3-oxazolidine-2-thione to 4-substituted N-crotonyl 1,3-oxazolidin-2-ones furnished Michael addition products. A perfect match occurred when both Michael donor and acceptor possessed the same stereochemistry and a mismatch when they had opposite stereochemistries. The newly created stereochemical center was shown to be governed by the Michael donor and not by the acceptor. (C) 2012 Elsevier Ltd. All rights reserved.

Environmentally Friendly and Regioselective One-Pot Synthesis of Imines and Oxazolidines Serinol Derivatives and Their Use for Rubber Cross-Linking

High-yield regioselective synthesis of imines and oxazolidines derivatives of 2-amino-1,3-propandiol (serinol) was achieved by performing the reaction with aldehydes and ketones, in the absence of solvents and catalysts. Only imines were obtained when the carbonyl compound was aromatic and/or sterically hindered and when conjugated double bonds were formed. 1,3-Oxazolidines were specifically obtained with either aldehydes or ketones with limited steric hindrance. The green reaction conditions here adopted for the synthesis of these classes of derivatives are not due to the structural and functional peculiarity of the serinol as a reactant and can also be extended to lipophilic amines with the same good results in terms of yield and selectivity. A revision of the mechanism typically accepted in the presence of solvent and catalysis is proposed, and the quantum mechanics calculations applied to some derivatives are in good agreement with the proposed rationalizations of the selectivity observed. Serinol itself and the imine and oxazolidine derivatives were used, in place of guanidine, as accelerators in compounds based on diene rubbers and silica, suitable for application in tire treads with low environmental impact. Efficient sulfur-based cross-linking and composites with a low dissipation of energy were obtained. The oxazolidine and imine appear to act as protective groups of the serinol primary amine. This work paves the way for the selective synthesis of biosourced families of chemicals, which could be used for large-scale applications, such as the one in rubber compounds, replacing toxic oil-based chemicals.

Enantiomeric pairs of ternary copper(ii) complexes and their aldol-type condensation products: synthesis, characterization, and anticancer and epigenetic properties

Chiral enantiomers [Cu(phen)(l-ser)(H2O)]NO(3)1 and [Cu(phen)(d-ser)(H2O)]NO(3)2 (ser = serinato) underwent aldol-type condensation with formaldehyde, with retention of chirality, to yield their respective enantiomeric ternary copper(ii) complexes, viz. l- and d-[Cu(phen)(OCA)(H2O)]NO(3)xH(2)O (3 and 4; phen = 1,10-phenanthroline; OCA = oxazolidine-4-carboxylate; x = 1/2, 0-2) respectively. These chiral complexes were characterized by FTIR, elemental analysis, circular dichroism, UV-visible spectroscopy, fluorescence spectroscopy (FL), molar conductivity measurement, ESI-MS and X-ray crystallography. The crystal structures of 1 and 3 showed both the cationic complexes to have a square pyramidal geometry. These complexes were about nine fold more potent than cisplatin against metastatic MDA-MB-231 breast cancer cells, inducing apoptotic cell death via ROS generation and a massive drop in mitochondrial membrane potential. The results of monitoring EZH1, EZH2 and H3K27me3 revealed that the mode of action of 1-4 also involved the downregulation of EZH2 and it seemed to be independent of the H3K27me3 status.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 34052-90-9 is helpful to your research. COA of Formula: C12H12N2O2.
