| titleOfInvention | Novel 7alpha-methoxycephalosporin compound |
| abstract | NEW MATERIAL:The titled compound of formula I [R is aryl, (aryl-substituted) lower alkyl, or halogen-substituted lower alkyl; A is H, (acetoxy)methyl, or heterocyclic thiomethyl], and its derivative at the carboxyl group. n EXAMPLE: 7α-Methoxy -7β- [ 2-( p-toluenesulfonyloxy )acetamido]cephalosporanic acid (salt). n USE: Intermediate of 7α-methoxycephalosporin compound which is an antimicrobial agent effective to resistant microbials. n PROCESS: For example, a compound of formula II or its derivative at the amino group or carboxyl group is made to react with a sulfonyloxyacetic acid of formula III or its reactive derivative at the carboxyl group, and the resulting compound of formula IV is treated with a halogenating agent in the pesence of an alkali metal salt of methanol (pref. lithium methoxide) and methanol to obtain the objective compound of formula I. n COPYRIGHT: (C)1981,JPO&Japio |
