Abstract

Abstract α-Amino-ϵ-caprolactam (I), an intermediate for the synthesis of L-lysine, has been synthesized by B ECKMANN-rearrangement of α-amino-cyclohexanoneoxime (XII) in concentrated sulfuric acid (13% yield) or oleum (34% yield). Cyclisation of α-amino-ϵ- bromocaproamide hydrobromide (VIII) did not yield I but an isomer of I of unknown structure (compound X). Upon hydrolysis X gave a compound XI which was similar to lysine in its ...
