  Convenient Formation of Diphenylmethyl Esters Using Diphenylmethyl Trichloroacetimidate

  摘要：

  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 acid substrates undergo esterification in excellent yields with the trichloroacetimidate reagent, including substrates possessing acid- or base-sensitive functionality. Protection of a carboxylic acid with a highly enolizable alpha-stereocenter using diphenylmethyl imidate was also accomplished without racemization.
