  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.

  Trichloroacetimidates are useful reagents for the synthesis of esters under mild conditions that do not require an exogenous promoter. These conditions avoid the undesired decomposition of substrates with sensitive functional groups that are often observed with the use of strong Lewis or Brønsted acids. With heating, these reactions have been extended to benzyl esters without electron-donating groups. These inexpensive

  三氯乙亚氨酸酯是在温和条件下合成酯的有用试剂，不需要外源促进剂。这些条件避免了带有敏感官能团的底物发生不希望的分解，这种分解通常在使用强路易斯酸或布朗斯台德酸的情况下观察到。通过加热，这些反应已扩展为不具有给电子基团的苄基酯。这些廉价且方便的方法应在复杂基质中酯的形成中找到应用。
