On the basis of chemical and stereochemical evidence the course of the formation of 4-acyl-β-lactams from 1,2-iminoketones by reaction with the acyl chloride/Et3N system or with the preformed ketene is discussed.
Syntheses of N-substituted 3,3,4-triphenyl-4-benzoylazetidin-2-ones and 3',3'-diphenyl spiro(acenaphthen-1-one-2,4'-azetidin-2'-ones); novel examples exhibiting a high reactivity of imino group in ketoimines

The reaction of 2-diazo-1,2-diphenylethanone (1) with 2-imino-1,2-diphenylethanones 2a-e gave new N-substituted 3,3,4-triphenyl-4-benzoylazetidin-2-ones 3a-e, together with 1,1',2,2'-tetraphenyl-2,2'-azinodiethanone (4).Similar reaction of 1 with 2-iminoa
