Stereoselective, temperature-dependent [2+2] cycloaddition of N,N-dialkylhydrazones to N-benzyl-N-(benzyloxycarbonyl)aminoketene

The Staudinger-like [2+2] cycloaddition of aliphatic hydrazones derived from (2R,5R)-1-amino-2,5-dimethylpyrrolidine to N-benzyl-N-(benzyloxycarbonyl) aminoketene takes place to afford the corresponding β-lactams in good yields when iPr2EtN is
