PROCEDURE

实验过程

The 3-halo-3-cephem esters represented by the above formula II when Y is chloro or bromo are also prepared with the 3-hydroxy-3-cephem esters as described by R. R. Chauvette et al., J. Amer. Chem. Soc., 96, 4986 (1974). For example, p-nitrobenzyl 7-[2-(2-thienyl)acetamido]-3-hydroxy-3-cephem-4-carboxylate is reacted with thionyl chloride in dry DMF to yield p-nitrobenzyl 7-[2-(2-thienyl)acetamido]-3-chloro-3-cephem-4-carboxylate.
