A new asymmetric phase-transfer catalyst is described, along with a new, flexible synthetic scheme using a tartaric acid chloride. Alkylations and Michael reactions on a glycine imino ester show the new catalyst to be an effective phase-transfer catalyst with limited enantioselectivity. (C) 2004 Published by Elsevier Ltd.
