Abstract

A procedure to prepare new cefem compounds. The compound (I) or a salt of the compound with the compound r <011> is reactioned. If needed, the resultant compound may be submitted in which r is carboxi (lower) - protected right, a reaction of the removal of the carboxi protection group to give the composite in which r is carboxi (lower) rent or submit the resultant compound in which r is (lower) rent a reaction of elimination of the hydroxy protective group to give the composite in which r is hydrogen. Compound (II) is obtained. (Machine-translation by Google Translate, not legally binding)
