Highly enantio- and diastereoselective (Ipc)2BOTf mediated aldol reactions of morpholine carboxamides are described. A wide variety of α-substituted N-acyl morpholine carboxamides were successfully employed, including α-bromo, α-chloro, α-vinyl and para-methoxyphenyl morpholine carboxamides which provided the corresponding aldol products in moderate to excellent yields, and generally with high enantio-
