摘要
Tertiary amines bearing an hydroxyethyl group derived from phenylglycinol, norephedrine or norpseudoephedrine can be selectively dealkylated using a two-step sequence involving treatment with thionyl chloride in THF, followed by reaction with an excess of potassium cyanide in THF:DMSO. These conditions are compatible with the presence of an insaturation or a benzyl ether in the substrate. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
