Total Synthesis of 3-(5-Tetrazolyl)carbapenems

The synthesis of the title compounds, β-lactam antibiotics, is described.A new tetrazole protecting group, (((p-nitrobenzyl)carbonyl)oxy)methyl, was succesfully applied.Substitution of carboxyl by tetrazole on the carbapenem nucleus results in stability to a degradative renal enzyme.
