Abstract
NEW MATERIAL:An azetidinone derivative shown by formulaI(R1 is aryl-lower alkyl, aryloxy-lower alkyl; R2 is aryl-lower alkyl in which the phenyl ring may have nitro groups, lower alkyl which may be substituted with halogen atoms; R3 is lower alkyl).
USE: Synthetic intermediate of penicillin or cephalosporin antibiotics.
PREPARATION: For example, an azetidinone derivative of formula II (R4 is 2- benzothiazolyl) is treated electrolytically in the presence of a lower alcohol to give the compound of formulaI.
