The invention provides 7-trichloroacetamido-3-desacetoxy-cephalosporanic acid derivatives of the formula: ##SPC1## Wherein R is a group which protects the carboxylic acid radical, which can be converted into 7-amino-3-desacetoxycephalosporanic acid by replacing the R-- and Cl.sub.3 C--CO-- radicals by hydrogen atoms.
该发明提供了式为:##SPC1##
其中R是保护羧基的基团,可以通过将R-和Cl3C-CO-基团替换为氢原子来转化为7-氨基-3-去乙酰基头孢菌素酸的7-三氯乙酰胺基-3-去乙酰基头孢菌素酸衍生物。
