Article abstract of DOI:10.1016/S0040-4020(01)85890-7

The total synthesis of two 4-ethoxycarbonyl cephems is described.For one of these, an amino group at the 7 position, protected as a phtalimido, is introduced.This modification provides a structure which closely resembles that of biologically active cephal
