Synthesis of β-lactams via cycloaddition of hydrazones with phenoxyketene
Sharma,Pandhi
, p. 2196 - 2200 (2007/10/02)
Phenoxyketene is capable of annelating the disubstituted hydrazones to afford stereoselectivity cis-monocyclic β-lactams with a 1-amino functionality. The ease of cycloaddition is governed by substitutents on the azomethine carbon as well as on the hydraz
