Synthesis and Rearrangement of Dispiro-Epoxy-β-Lactams

Synthetic Communications, 1992
Abstract α-Methylene-β-lactams are prepared by a Peterson olefination reaction. These substrates can be epoxidized with MCPBA to give the title dispiro-epoxy-β-lactams. Under the influence of boron trifiuoride, these substrates rearrange to spiro-3-ketolactams.
