| abstract |
NEW MATERIAL:A compound shown by formula I [R 1 is organic group reductively eliminable under acidic condition; R 2 and R 5 are H or carboxyl- protecting group; R 3 is alkyl, OH, methoxy or acetoxy; R 4 is ethyl, i-propyl or CH 3 CR 6 (OR 7 ) (R 6 is H or methyl; R 7 is OH-protecting group)]. n EXAMPLE: 2(S)-Benzyloxycarbonylamino-5-keto-6-t-butyloxycarbonyl-octanoic acid benzyl ester. n USE: An intermediate for producing carbapenam or carbapenem such as β-lactam antibiotics, etc., having excellent antibacterial action. n PREPARATION: A lithium enolate of a carboxylic acid ester shown by formula III is added to a pyrrolidonecarboxylic acid ester shown by formula II containing protected amino group and carboxyl group, which is subjected to ring formation to give a compound shown by formula I. n COPYRIGHT: (C)1988,JPO&Japio |
