## Abstract Es wird eine neue Synthese von β‐Lactamen durch Umsatz von 4‐Alkylazlactonen mit acyclischen Iminen beschrieben. Mit einem cyclischen Imin wird dagegen ein Imidazolin‐Derivat erhalten.
N-Benzyloxyimines have been shown to react with ketene silyl acetals in the presence of trimethylsilyl triflate catalyst to give alkyl B-benzyloxyaminocarboxylates. Conversion of them to f3-lactams has been exemplified. Synthesis of N-unsubstituted and N-hydroxylated B-lactams is an important subjec
