Mild acetal cleavage using B-chlorocatecholborane in the synthesis of rearrangement-sensitive 2-arachidonoylglycerol
摘要:
d A mild method for the cleavage of an acetal to afford a rearrangement sensitive diol using B-chlorocatecholborane was developed for the synthesis of the endogenous cannabinoid neurochemical messenger 2-arachidonoylglycerol. The tendency for rearrangement of 2-arachidonoylglycerol to the corresponding 1-arachidonoylglycerol was precluded with this reagent. Features of the partial recyclization to an isomeric acetal provide mechanistic detail. (C) 2012 Elsevier Ltd. All rights reserved.
