Process for the preparation of antibacterial compounds of the formula ##STR1## comprises condensing an oxo compound of the formula ##STR2## with an amino compound of the formula ##STR3## to produce a compound of the formula ##STR4## reacting the compound of the formula (III) with a compound of the formula ##STR5## to give a compound of the formula ##STR6## and then eliminating the amino-protective group ##STR7##
制备抗菌化合物的过程包括将公式为##STR1##的酮化合物与公式为##STR2##的
氨基化合物缩合,产生公式为##STR4##的化合物,然后将公式为(III)的化合物与公式为##STR5##的化合物反应,得到公式为##STR6##的化合物,最后消除
氨基保护基##STR7##。
