Intermediates useful in the production of cephem prodrug esters |
| abstract |
(57) [Summary] (Modified) [Objective] This compound provides an intermediate useful for the production of a cephem prodrug ester. [Structure] A compound represented by the formula I, a compound represented by the formula V, a C 1 -C 4 alkyl ester thereof and the like, and a method for producing them. Wherein R 2 is an O-protecting group of the type commonly used in the synthesis of cephalosporin compounds, R 3 is hydrogen or methyl and R 4 is hydrogen or a physiologically hydrolyzable ester residue. ] |
