Synthesis of aryl 2-benzofuranyl and aryl 2-indolyl carbinols of high enantiomeric purity via palladium-catalyzed heteroannulation of chiral arylpropargylic alcohols
摘要:
2-Iodophenol and 2-iodo-N-mesylaniline have been reacted with alpha-arylpropargylic alcohols of high enantiomeric purity under transition-metal catalysis leading to aryl 2-benzofuranyl and aryl 2-indolyl carbinols in good yield and high enantiomeric excess, thus constituting the first enantiospecific synthesis of these important classes of compounds.

Aryl propargylic alcohols of high enantiomeric purity via lipase catalyzed resolutions
摘要:
A variety of substituted aryl propargylic alcohols were prepared via lipase catalyzed resolutions, the enantioselective hydrolysis of the corresponding esters being the method of choice. Copyright (C) 1996 Elsevier Science Ltd
