The base induced cyclisations of azoacetates to azetidinones were investigated. In addition to the isolation of the desired products, it was found that 2-iminopyrrolidine-5-one derivatives as well as N-acyl hydrazides could be isolated when metal cyanides were employed as base. These entities were further modified to form pyrrolidine-2,5-diones and diazetidinones respectively. The Japan Institute of Heterocyclic Chemistry.

The azoacetates derived from aryl hydrazones of α,α-disubstituted-β-ketoamides are readily transformed into azetidinones or diazetidinones.
