ABSTRACT:
New and useful cephem compounds derived from cephalosporin C are provided by this invention, which are valuable as intermediate for the synthesis of another bacteriocidally active cephem derivatives and which are readily extractable from its aqueous solution by means of an organic solvent and enable the cephalosporin C content in the aqueous fermentation broth filtrate to be recovered at an improved yield. Cephalosporin C present in the fermentation broth may be converted into the cephem compounds of this invention by reacting with a substituted chloroformate compound within said filtrate, and the cephem compounds so formed may then be extracted therefrom with an organic solvent. The cephem compounds of this invention further may be converted into a 7-acylamidocephalosporanic acid or 7-aminocephalosporanic acid through some successive reactions.
