Abstract

PURPOSE: 1-Substituted-3-acylamino-2-azetidinones having acyloxy group expressed by the formula I: (R is an aryl, heterocyclic group; R4 is and acyl; R2' and R3' are H, or R2' and R3' form acyloxyimino expressed by the formula=NOR4 together). For example, 1-(4-benzouloxy-α-carboxybenzyl)-3-(2-benzoyloxyimino-2-phenylacetamide)-2-azetidinone.
