Penicillin G sulfoxide diphenyl methyl ester synthesis method

The invention discloses a penicillin G sulfoxide diphenyl methyl ester synthesis method, which comprises: esterifying a penicillin G potassium salt as an initial raw material, and oxidizing through 2KHSO5.KHSO4.K2SO4 to synthesize the penicillin G sulfoxi

2,4,6-TRIPYRIDINIO-1,3,5-TRIAZINE TRICHLORIDE, A NEW AND MILD ESTERIFICATION AGENT FOR PREPARATION OF PENICILLIN ESTERS

Cyanuric chloride reacted with 3-molar equivalents of pyridine to give 2,4,6-tripyridinio-1,3,5-triazine trichloride, which was found to condense penicilins with alcohols under mild conditions to afford penicillin esters in good yields.Application to prep
