An effective ‘promoter control’ on enantioselective acyclic stereoselection based on chiral oxazaborolidinone-promoted asymmetric aldol reactions has been found in the case of chiral N-protected α-amino aldehydes. An enantioselective synthesis of the title compound has been efficiently accomplished by using a sequence of the aldol reaction.
