Process for preparing optically active [(3-amino-3-carboxy)propyl-1]phosphinic acid derivatives

摘要

Disclosed is a novel process for optically active [(3-amino-3-carboxy)propyl-1]phosphinic acid derivatives, which comprises reacting a Shiff's base with a derivative of vinylphosphinate in the presence of a base, and subjecting the resulting compound to hydrolysis to form the optically active [(3-amino-3-carboxy)propyl-1]phosphinic acid derivatives as either [L-(3-amino-3-carboxy)propyl-1]phosphinic acid derivatives or [D-(3-amino-3-carboxy)propyl-1]phosphinic acid derivatives.
