Abstract
NEW MATERIAL:A compound expressed by the formula (R<1> represents alkyl, aralkyl or aryl; R<2> represents H or carbamoyl which may be protected; R<3> represents H or ester). EXAMPLE:7-t-butoxycarbonylaminocepholosporanic acid. USE:An intermediate for synthesis of cephalosporin compounds useful as an antibacterial agent, etc. PREPARATION:(A) The corresponding 7-substituted-oxycarbonylaminocepha losporanic acid is hydrolyzed with alkanol-water-alkali metal hydroxide and (B) thus obtained corresponding 7-substituted-oxycarbonyl-amino-3- hydroxymethylcephem-4-carboxylic acid is carbamoylated. (C) The corresponding 7-substituted-oxycarbonylamino-3-carbamoyloxymethylcephem-4-carboxyic acid is then esterified to afford the aimed cephem compound.
