Abstract

NEW MATERIAL:A chlorinated azetidinone derivative expressed by formulaI R1 is arylmethyl or aryloxymethyl; R2 is lower alkyl, arylmethyl or aryloxymethyl which may have a halogen as a substituent group; R3 is expressed by formula II (R4 is lower alkyl), formula III, -S-SO2-R5 (R5 is aryl), etc.].
USE: An intermediate for preparing penicillin or cephalosporin antibiotic substances.
PROCESS: An azetidinone derivative expressed by formula VI including partially a novel compound is electrolyzed in the presence of hydrochloric acid, or a chloride, etc. to give the compound expressed by formulaI.
