A Convenient Preparation of N-Acyl-1, 2-dihydroquinoline

Abstract

N-Acetyl- and N-formyl-1, 2-dihydroquinoline were conveniently prepared by reductive acylation of quinoline without isolating the labile 1, 2-dihydroquinoline. This method was also applied to isoquinoline to prepare N-acetyl-1, 2-dihydroisoquinoline.
