6β(7β)-(N-2,2,2-Trichloroethoxycarbonyl-N-trifluoromethanesulphonylamino) penicillins and cephalosporins have been converted into the corresponding 6α(7α)-formamido-6β(7β)-2,2,2-trichloroethoxycarbonylamino derivatives, by treatment with N,N-bis(trimethylsilyl) formamide and triethylamine.
6β(7β)-(N-2,2,2-三氯乙氧基羰基-N-三氟甲烷磺酰氨基)青霉素和头孢菌素已转化为相应的6α(7α)-甲酰胺基-6β(7β)-2,2,2-三氯乙氧基羰基氨基衍生物,通过用N,N-双(三甲基甲硅烷基)甲酰胺和三乙胺处理。
