摘要
The Mannich reaction of titanium enolates of a chiral hydantoin with various aldimines smoothly occurred in good yields and with high anti-diastereoselectivity. The Mannich adducts can be readily cleaved by alcoholysis to afford several beta-amino ester derivatives in good yields and in almost enantiomerically pure form.
