Abstract

NEW MATERIAL:A compound of formulaI[R1 is arylmethyl, aryloxymethyl; R2 is lower alkyl, arylmethyl, which may be substituted with halogen; R3, R4 are lower alkyl, phenyl].
USE: Synthetic intermediate of cephalosporins, antibiotics.
PREPARATION: An azetidinone derivative of formula II and a phosphite ester of formula III (R5 is lower alkyl, phenyl) such as trimethyl phosphite are allowed to react, preferably at a molar ratio of 1/(1.5W3) in an inert solvent such as benzene at -20W100°C.
