Abstract
The transformation of diazoketones to ketenes can be realized not only by utilizing photochemical reaction conditions but also under the action of microwave irradiation. In the presence of imines, the generated ketenes react further to afford β-lactams. Various trans-substituted β-lactams derived from amino acids have been prepared.
