Synthesis of Polyoxazolidines and Their Application in Polyurethane Modification

2,2-Dimethyl-N-hydroxyethyl-1,3-oxazolidine (OX) and two kinds of poly-oxazolidines based on OX:malonic acid diethyl-2, 2-dimethyl-N-hydroxyethyl-1, 3-oxazolidine ester (OX1) and 1, 1, 5, 5-pentane end tetracarboxylic acid tetra-2,2-dimethyl-N-hydroxyethyl-1,3-oxazolidine ester (OX2) have been designed and successfully synthesized. Their structures. have been confirmed by C-13-NMR, ESI-MS, elemental analysis and FTIR. Their applications as latent curing agents in single component polyurethane (SPU) systems have been investigated. The results show that the SPU system cured in air without oxazolidine forms lots of foaming and can be swelled, its tensile strength is 3.2 MPa and the elongation at break is 364%. However, the tensile strength and elongation at break of the SPU system cured with the synthesized OX2 can reach 27.2 MPa and 457%, about 9 times and 1.26 times as compared with those the cured SPU system without OX, respectively. The addition of the synthesized OX1 or OX2 can greatly improve the apparent performance, mechanical properties and thermal stability properties of the cured SPU system.

Oxazolidine Synthesis by Complementary Stereospecific and Stereoconvergent Methods

Complementary stereospecific and stereoconvergent reactions for enantioselective synthesis of 1,3-oxazolidines are reported. In the presence of a rhodium catalyst, reaction of enantioenriched butadiene monoxide with aryl imines is stereospecific (99% ee). Alternatively, the reaction of racemic butadiene monoxide, in the presence of a chiral palladium or nickel catalyst, provides an enantioselective synthesis of 1,3-oxazolidines (up to 94% ee). Synthesis of either the cis- or trans-1,3-oxazolidines is also accomplished under catalyst control.

2D-Coordination polymer containing lead(II) in a hemidirected PbO4S3 environment formed by molecular breaking of the 1,3-oxathiolane ligand

A new 1,3-oxathiolane-based ligand, 2-(1,3-oxathiolan-2-yl)pyridine, was prepared and its coordination to lead(II) was investigated. Experiments revealed a ligand-breaking reaction during the complexation process, which leads to the formation of a 2D-coordination polymer of lead(II), [Pb(mu(3)-HME)(mu-OAc)](n); H2ME: 2-mercaptoethanol. The compounds have been characterized by elemental analysis, FT-IR, H-1 NMR spectroscopy and single-crystal X-ray diffraction. X-ray analysis revealed a 2D-coordination polymer extending via acetato bridges. The lead(II) center adopts a rare PbO4S3-distorted pentagonal bipyramidal geometry with a hemidirected arrangement. Upon coordination, the thiol group of the H2ME ligand is deprotonated to coordinate as an anionic ligand. The network extends in sheets in the crystallographic ab plane via Pb-S-Pb and Pb-O-Pb bridges, aided by O-H center dot center dot center dot O hydrogen bonds.

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.

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.

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.
