Enantioselective deprotonation of ketones using a novel heterodimer chiral amide base
摘要:
A novel heterodimer chiral base system has been prepared and reacted with a series of prochiral ketones in the presence of TMSCl to give efficient formation of the corresponding enol ethers in an enantiomeric excess up to 85%. (C) 2003 Elsevier Ltd. All rights reserved.
