Convenient Formation of Diphenylmethyl Esters Using Diphenylmethyl Trichloroacetimidate

Diphenylmethyl trichloroacetimidate is a useful reagent for the protection of carboxylic acids as their corresponding diphenylmethyl esters. These esterifications proceed rapidly without the need for an added catalyst or promoter. A variety of carboxylic

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
