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.

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.

Catalyst-controlled diastereoselective ring-opening formal [3+2]-cycloadditions of arylvinyl oxirane 2,2-diesters with cyclic N-sulfonyl imines

A diastereoselectivity-controllable formal [3+2]-cycloaddition of arylvinyl oxirane 2,2-diesters with cyclic N-sulfonyl imines is developed, affording the corresponding tricyclic oxazolidine derivatives in moderate to excellent yields with excellent diastereoselectivities in the presence of palladium(0) or scandium(III) triflate.

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.

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.

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.

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.
