Enantioselective Conjugate Addition-Protonation of 5H-Oxazol-4-ones and 5-Methylene 1,3-Oxazolidine-2,4-diones: 2,2′-Biphenol-Induced Diastereoselectivity Switch

of main observation and conclusion A synthetic strategy for catalytic asymmetric conjugate addition-protonation and diastereoselective switch between 5H-oxazol-4-ones and 5-methylene 1,3-oxazolidine-2,4-diones was established. An array of chiral conjugate addition-protonation products bearing 1,3-O-heterotertiary-O-heteroquarternary nonadjacent stereocenters were obtained in excellent yields, moderate to good diastereoselectivities, and excellent enantioselectivities (up to 97% yield, 11: 1 dr, and 98% ee). Induction by 2,2′-biphenol could effectively promote the production of the corresponding diastereoisomers via cycloaddition intermedia.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 90319-52-1. Name: (R)-4-Phenyloxazolidin-2-one.

Solvent-Minimized, Chromatography-Free, Diastereoselective Synthesis of Oxazolidine-Dispirooxindoles via oxa-1,3-Dipolar Cycloaddition of 3-Oxindole

An efficient and diastereoselective decarboxylative oxa-1,3-dipolar cycloaddition between 3-oxindoles and diverse amino acids is developed to access novel oxazolidine-dispiroox-indole skeletons bearing vicinal quaternary carbon centers. This protocol features operational simplicity, a broad substrate scope, and good to excellent chemical yields and diastereoselectivities. In particular, minimal solvent (1 mL/10 mmol) and chromatography free purification render this synthetic process more efficient and environmentally benign in the context of green chemistry.

Stereoselective synthesis of pinane-type tridentate aminodiols and their application in the enantioselective addition of diethylzinc to benzaldehyde

A library of pinane-based aminodiols were prepared from commercially available (1R)-(-)-myrtenol (-)-1. Compound (-)-1 was transformed into ally! trichloroacetamide (+)-2 via the acetimidate, followed by the Overman rearrangement. In order obtain the aminodiol structure, (+)-2 was subjected to stereoselective dihydroxylation with OsO4, resulting in dihydroxy trichloroacetamide (+)-3. The trichloroacetyl group was removed from (+)-3 with aqueous HCl and the (1R,2R,3S,5R)-3-amino-2-hydroxymethyl-6,6-dimethylbicyclo[3.1.1]heptan-2-ol hydrochloride (-)-4 obtained was transformed to primary, secondary and tertiary aminodiols by reductive amination, N-alkylation of aminodiol (+)-9 and debenzylation of N-benzyl aminodiol (+)-10, respectively. In the reactions of (+)-9 and (+)-14 with formaldehyde, highly regioselective ring closure was observed. In contrast with earlier results, the aminodiols gave pinane-fused oxazolidines (+)-11 and (-)-15. The aminodiols and their oxazolidine derivatives 5-15 were applied as chiral catalysts in the enantioselective addition of diethylzinc to benzaldehyde. The best enantioselectivity was observed in the case of the N-benzyl-substituted derivative (+)-9. (C) 2012 Elsevier Ltd. All rights reserved.

Transition metal complexes of a versatile polyalkoxy oxazolidine-based ligand derived from in situ cyclization

One-pot reaction between 8-hydroxyquinoline-2-carboxaldehyde (HQC) and tris(hydroxymethyl)amino-methane (TRIS) followed by in situ cyclization yielded an oxazolidine based ligand which produced four mononuclear complexes of Mn-II(1), Co-II(2), Ni-II(3), Zn-II(4), a tetranuclear iron (Fe-4(III))) complex (5) and a tri-nuclear cobalt (CoIICo2III complex (6). Magnetic studies show dominant antiferromagnetic interaction in tetranuclear iron (Fe-4(III)) complex 5 and presence of the slow relaxation of magnetisation in 6. The compounds were also studied for their antibacterial properties. The oxazolidine ligand (H3L2) of this study showed good antimicrobial activity not only against Gram-positive bacteria but against Gram-negative bacteria too. The antimicrobial efficacy of the metal complexes (1-6) is also reported.

Palladium/copper-catalyzed multicomponent reactions of propargylic amides, halohydrocarbons and CO2 toward functionalized oxazolidine-2,4-diones

A palladium/copper-catalyzed oxy-carbonation of propargylic amides by halohydrocarbons and CO2 has been developed toward functionalized oxazolidine-2,4-diones. This multi-component reaction (MCR) was triggered by the oxidative addition of RX to Pd(0), followed by the sequential carboxylation of amide and trans-oxopalladation of an electron-deficient triple bond by RPdX species. Finally, the reductive elimination afforded products possessing tetra-substituted vinyl motifs and Pd(0). This protocol features simultaneous formation of three bonds, representing an efficient method for incorporation of CO2 into value-added heterocycles.

Understanding the mechanism, thermodynamic and kinetic features of the Kukhtin-Ramirez reaction in carbamate synthesis from carbon dioxide

In this article, thermodynamic and kinetic aspects of the Kukhtin-Ramirez reaction of the carbamate formation from carbon dioxide have been investigated in the presence of various phosphorous reagents (PRs), in the gas and solvent phases, theoretically. The obtained carbamate is a precursor for the synthesis of oxazolidine-2,4-dione as a biologically important compound. Two kinds of phosphorous reagents have been considered: type 1 is the PRs which have variable numbers of nitrogen atoms while, type 2 is composed of PRs without nitrogen atoms. By investigation of the local nucleophilicity indices (N-k) and steric exchange energy (dE), the reaction kinetics was studied in the presence of these kinds of PRs. It was illustrated that the steric repulsion between the lone pair electrons of the phosphorus atom and its bonded groups and the nucleophilicity character of this atom are impressive factors in the reaction kinetics. On the other hand, the analysis of stabilization energies associated with the donor-acceptor orbitals of the oxide forms of PRs (PORs) shows that the number of nitrogen atoms of the studied PRs have remarkable effects on the thermodynamics of the overall reaction. Finally, it has been shown that the obtained Delta E-Reaction by MPWB95 and B3LYP functionals, are in an acceptable correlation with the Mulliken atomic spin density (P-k(-)) of the phosphorous atom.
