Abstract

PURPOSE: A specific penicillin derivative is converted with trialkylsiiylper fluoroalkanesulfonate under mild conditions to produce the titled compound used as a synthetic intermediate of cephalexin in high yield.
CONSTITUTION: Penicillin sulfoxide of formula I (R1 is H, halogen, organic residual group; R2is H, alkyl) or sulfenic silyl ester or formula II (R3 is alkyl) is stood together with trialkylsilyl perfluoroalkanesulfonate of (R4)3SiO-SO2R5 (R4 is alkyl; R5 is perfluoroalkane) without heating to give the objective compound of formula III. An example of trialkylsilyl group is trimethylsilyl and of perfluoroalkanesulfonate is trifluoromethylsulfonate CF3SO3 -.
