| titleOfInvention | Diacyl penicillins and methods for their production |
| abstract | Novel diacyl penicillins of the formula O CH2-C ANGLE S ANGLE CH3 N-CH-CHC ANGLE ¦¦¦CH3 R-C ANGLE ¦¦¦ O¦¦¦ O=C--N---CH-COOX (I) wherein R is alkyl, cycloalkyl, aryl, aralkyl, phenoxyalkyl, heterocyclic carboxyl excepting isoxazole carboxyl derivatives, or IN WHICH BENZENE RING A may optionally be substituted and B represents a protective group for the amino group, and X is a protective group for the carboxyl group, are produced by reacting a benzyl penicillin ester of the formula S ANGLE CH3 CH2-CO-NH-CH-CHC ANGLE ¦¦¦CH3 O=C--N---CH-COOX (II) wherein X is as defined above, with a chlorinating agent in the presence of tertiary organic base to obtain an imide chloride group-incorporated compound of the formula S ANGLE CH3 CH2-C=N-CH-CHC ANGLE ¦¦¦¦CH3 ClO=C--N---CH-COOX, (III) and then reacting the compound of the last-named formula with carboxylate of the formula R-COOM (IV) wherein M is a metal atom, and R is as defined above. |
