Enantioselective Addition of Diethylzinc to Aldehydes by Chiral Oxazolidine-Titanium Complex

A series of chiral oxazolidines derived from (1R, 2S)-cis-1-amino-2-indanol was found to be effective in promoting the asymmetric addition of diethylzinc to aldehydes. Among the ligands developed, it was found that ligand 1b in the presence of Ti((OPr)-Pr-i) 4 yielded the highest enantioselectivities when it was applied in the catalytic asymmetric addition of diethylzinc to aldehydes (up to 91% ee).

Synthesis and characterization of different types of epoxide-based Mannich polyols from low-cost cashew nut shell liquid

Cashew nut shell liquid (CNSL) is a natural aromatic organic oil consisting of phenolic compounds with interesting structures. Extraction of CNSL was performed in a Soxhlet apparatus. The major (90 %) component of CNSL is anacardic acid, which is easily decarboxylated to cardanol (10 %) by use of conventional methods. In this paper we describe a three-step synthesis of Mannich polyols for rigid foams. The first step is synthesis of N-(2-hydroxyethyl)-1,3-oxazolidine (the Mannich precursor) by condensation of paraformaldehyde and diethanolamine. The second step involves synthesis of the Mannich base phenolic ring of cardanol by reaction with N-(2-hydroxyethyl)-1,3-oxazolidine. The third step is alkoxylation. The synthesized polyols were characterized by FTIR and H-1 NMR spectroscopy and thin-layer chromatography.

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 16251-45-9. Name: (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one.

Spirocyclic Nitroxides as Versatile Tools in Modern Natural Sciences: From Synthesis to Applications. Part I. Old and New Synthetic Approaches to Spirocyclic Nitroxyl Radicals

Spirocyclic nitroxyl radicals (SNRs) are stable paramagnetics bearing spiro-junction at alpha-, beta-, or gamma-carbon atom of the nitroxide fragment, which is part of the heterocyclic system. Despite the fact that the first representatives of SNRs were obtained about 50 years ago, the methodology of their synthesis and their usage in chemistry and biochemical applications have begun to develop rapidly only in the last two decades. Due to the presence of spiro-function in the SNRs molecules, the latter have increased stability to various reducing agents (including biogenic ones), while the structures of the biradicals (SNBRs) comprises a rigid spiro-fused core that fixes mutual position and orientation of nitroxide moieties that favors their use in dynamic nuclear polarization (DNP) experiments. This first review on SNRs will give a glance at various strategies for the synthesis of spiro-substituted, mono-, and bis-nitroxides on the base of six-membered (piperidine, 1,2,3,4-tetrahydroquinoline, 9,9 ‘(10H,10H ‘)-spirobiacridine, piperazine, and morpholine) or five-membered (2,5-dihydro-1H-pyrrole, pyrrolidine, 2,5-dihydro-1H-imidazole, 4,5-dihydro-1H-imidazole, imidazolidine, and oxazolidine) heterocyclic cores.

Stereoselective synthesis and application of tridentate aminodiols derived from (+)-pulegone

A library of tridentate aminodiols, derived from naturally occurring (R)-(+)-pulegone, was synthesized and applied as chiral catalysts in the addition of diethylzinc to benzaldehyde. The reduction of pulegone furnished pulegol, which was transformed into allylic trichloroacetamide via Overman rearrangement of the corresponding trichloroacetimidate. The protected enamine was subjected to dihydroxylation with OsO4/NMO system resulting in a 1:1 mixture of (1R,2R,4R)- and (1S,2S,4R)-aminodiol diastereomers. After the removal of the trichloroacetyl protecting groups, the obtained primary aminodiols were transformed into secondary ones. The regioselectivity of the ring closure of the N-benzyl substituted aminodiols with formaldehyde was investigated resulting in both the 1,3-oxazine and oxazolidine rings. The tautomerism of the spiro and fused ring systems was observed and its mechanism was studied by detailed DFT analysis by employing an IEFPCM solvent model to provide a more realistic representation of the experimental conditions. The obtained potential catalysts were applied to the reaction of benzaldehyde and diethylzinc with moderate to good enantioselectivity (up to 90% ee). (C) 2016 Elsevier Ltd. All rights reserved.

Total Synthesis and Bioactivity of ent-homospisulosine and N,O-diacetylhomoclavaminol A

Background: Over the past decade, simple 1-deoxysphingoid bases with a saturated hydrocarbon sidechain such as spisulosine, xestoaminol C, 3-epi-xestoaminol C, clavaminol A have attracted considerable attention from synthetic organic chemists because of their impressive cytotoxic/antiproliferative properties as well as the unique structures possessing a variously configured vicinal amino alcohol motif. Results: The stereoselective total synthesis of two deoxysphingosines ent-homospisulosine and N, Odiacetylhomoclavaminol A has been accomplished via a common approach. The key steps were a substrate controlled aza-Claisen rearrangement to install the C-N bond together with the required erythro arrangement of the neighbouring amino and hydroxyl functionalities. Further, the spontaneous intramolecular addition to the -NCS moiety proceeded regioselectively to form the requisite oxazolidine-2-thione skeleton. The employed Wittig olefination then completed the carbon backbone of the target molecules. Conclusions: Several newly prepared compounds was assessed for their antiproliferative/cytotoxic activity against six cancer cell lines (Jurkat, HeLa, MDA-MB-231, MCF-7, HTC-116 and Caco-2) using the MTT assay. On the basis of the observed potency, three structures were taken up for further investigation.

Atropo- and Diastereoselective Construction of Tetracyclic Biphenylazepinium Salts Derived from Aminoalcohols: Use as Catalysts in Enantioselective Asymmetric Epoxidation

A range of new biphenylazepinium salt organocatalysts effective for asymmetric epcondation has been developed incorporating an additional substituted oxazolidine ring, and providing improved enantiocontrol in alkene epoxidation over the parent structure. Starting from enantiomerically pure aminoalcohols, tetracydic iminium salts were obtained as single diastereoisomers through an atroposelective oxazolidine formation.
