A facile lipase catalyzed access to fatty acid monoesters of
摘要:
2-O-beta-D-glucopyranosylglycerol was submitted to acylation using Pseudomonas cepacia lipase as catalyst and 2,2,2-trifluoroethyl esters of various long chain carboxylic acids as acyl carriers. Monoacylation was easily accomplished with preferred formation of the (2S)-1-O-acyl derivatives in reactions showing high regio- and diastereoselectivity. (C) 1996 Elsevier Science Ltd

Short Regioselective Chemoenzymatic Synthesis and Biological Evaluation of 1-<i>O</i>-Acyl-2-<i>O</i>-(β-<scp>D</scp>-sulfoquinovopyranosyl)-<i>sn</i>-glycerols
convenient chemoenzymatic synthesis of a new class of non-natural sulfo-glycolipids – 2-O-(β-D-sulfoquinovosyl)-monoacylglycerols (2-O-β-D-SQMG) – derived from 2-O-(β-D-glucopyranosyl)glycerol and carrying acyl chains ofvarious lengths at the 1-position of the sn-glycerol moiety, was performed with the aid of a key step involving regioselective lipase-catalyzed acylation of 2-O-(6-deoxy-6-tosyl-β-D-gl
