Abstract

PURPOSE:To obtain the titled compound useful as a synthetic precursor for carbapenam antibiotic substance having high optical purity, advantageously on an industrial scale, by reacting a specific lithium enolate compound with a specific propynal imine derivative. CONSTITUTION:The objective compound of formula II is produced by reacting a lithium enolate compound of formula I (R<1> is lower alkyl or aryl; R<2> is alkyl) with a propynal imine derivative of formula R<3>CidenticalC-CH=NR<3> (R<3> is trialkylsilyl). The starting raw material of formula I can be produced by reacting a beta-hydroxybutyric acid ester of formula II with a dialkylzinc of formula ZnR<2> and reacting the resultant alkylzinc alcoholate with lithium diisopropylamide and/or lithium hexamethylenedisilazane.
