STEREOSPECIFIC AND NON-HAZARDOUS SYNTHESIS OF CIS AND TRANS-3-PHENOXYACETAMIDO-4-(2-ACETOXY-1,1-DIMETHYLETHYL)-AZETIDIN-2-ONES KEY INTERMEDIATES FOR THE SYNTHESIS OF 6-AMIDO-1,1-DIMETHYL-CARBAPEN-2-EMS

The title compounds have been prepared by a four-step sequence from 3-acetoxy-2,2-dimethyl-1-propanal and a novel non-hazardous and stereospecific route to cis-3-amido-azetidin-2-ones by the use of N-benzyl-2-carbobenzoxyglycine is described.
