Abstract:Penicillin G sulfoxide diphenylcarbinol ester was synthesized by penicillin G potassium salt. The yield of penicillin G sulfoxide was 97.3% under the conditions which the molar radio of acetic hydroperoxide to penicillin G potassium was 1.2∶1.0,the oxidization temperature was 0~5℃,and the reaction time was 2 h;The optimal conditions of esterification was the amount of penicillin G sulfoxide and methylene chloride were 1 g and 17 mL,the molar radio of diphenylcarbinol to penicillin G sulfoxide was 1.8∶1.0,the reaction temperature was -15℃,the reaction time was 60 min,the yield of penicilin G sulfoxide diphenylcarbinol ester was 79.5%,and the total yield was 77.4%. This technology was suitable to industrial production because of cheapness and safety.
Key words:penicillin G potassium salt;diphenylcarbinol;penicillin G sulfoxide diphenylcarbinol ester;synthesis
