摘要：

A new approach to the synthesis of monocyclic beta-lactam derivatives is presented. Dipolar cycloaddition of an aldonitrone with TMS-acetylene provided a 5-(trimethylsilyl)is oxazoline. The isoxazoline was fragmented with tetrabutylammonium fluoride (TBAF) to provide monocyclic beta-lactam derivatives in modest yield. Fragmentation of the isoxazoline with aqueous HF provides excellent yields of alpha,beta-unsaturated amides.
