Abstract
1302015 Cephalosporins ELI LILLY & CO 5 Nov 1970 [13 Nov 1969] 52755/70 Heading C2A A method for the cleavage of the 7-carboxamido group of a cephalosporin of Formula I wherein R is aminoadipoyl, C 2 -C 8 alkanoyl, a group of Formula II, III or IV X is C 2 -C 6 alkanoyloxy, C 2 -C 6 thioalkanoyloxy, C 6 -C 12 thioaroyloxy, hydroxy, mercapto, hydrogen, C 1 -C 6 alkoxy or C 1 -C 6 alkylthio, Y is O, S or a carbon-to-carbon bond; n is an integer of 0-3 and is at least 1 when Y is O or S; m is an integer of 1 to 3 and Q is amino or hydroxy; comprises blocking the carboxyl, amino, hydroxy and mercapto groups in the molecule, treating the blocked cephalosporin with a halogenating agent to convert the 7 -carboxamido group to an imino halide, treating the imino halide with an alkanol or benzyl alcohol to form an imino ether, and hydrolysing the imino ether to form a 7-amino group and blocking the carboxyl groups by converting them to a mixed anhydride derived from an acid having the formula R<SP>1</SP>-COOH, wherein R<SP>1</SP> is C 1 -C 8 alkyl, alkenyl or alkynyl or a group of Formula V or VI wherein Y is O, S or a carbon-to-carbon bond, n is an integer of 0 to 3 and is at least 1 when Y is O or S ; Z is O, S or and m is an integer of 1 to 3. The invention also comprises blocked cephalosporins of general formula VII whose carboxyl groups are blocked by converting them to a mixed anhydride derived from an acid which has the general formula R<SP>1</SP> being defined as above.
