Abstract
In this paper we propose the synthesis of 1-(2,4-dimethoxyphenyl)-4-(4-nitrophenyl)-3- phenoxyazetidin-2-one as a new monocyclic β-lactam. Its structure has been confirmed by IR, 1H-NMR, 13C-NMR and Mass spectroscopic data. In addition to its synthesis we present AM1 calculations to characterize the physical [...] Read more.
