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.

Application

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

A synthesis of optically pure densely functionalized gamma-lactams starting from 2-azetidinone-tethered iminophosphoranes has been developed. Full chirality transfer has been accomplished from the enantiomerically pure 2-azetidinones. The addition of lithium acetylides to 4-oxoazetidine-2-carbaldehydes at -78 degrees C smoothly yielded propargylic
