2-Azetidinone Usage And Synthesis

Uses

2-Azetidinone was used in synthesis of optically pure densely functionalized γ-lactams.

Definition

ChEBI: An unsubstituted beta-lactam compound.

General Description

2-Azetidinone is an unsubstituted four membered lactam. 2-Azetidinone is the fundamental building block of β-lactam antibiotics. X-ray photoelectron spectra of 2-azetidinone was investigated. 2-Azetidinone undergoes hydrolysis with aqueous alkali to yield β-alanine.
