effective strategy for the stereoselective synthesis of difluorinated building blocks. The benzodithiol group is a versatile and chameleonic group that can be further functionalized before fluorination, giving customized and tailored useful synthetic strategies. As an example of the application of this facile strategy, the effective enantioselective synthesis of difluoroarundic acid is described.
实用的和高度对映选择性的有机催化反应的结合,允许立体选择性地引入苯并二硫醇基团以及氟化步骤,为立体选择性合成二氟化结构单元提供了一种新的有效策略。苯并二硫醇基团是一种多官能且具有香油基的基团,可以在氟化之前进一步官能化,从而提供定制的和量身定制的有用合成策略。作为这种简便策略的应用实例,描述了二氟金刚烷酸的有效对映选择性合成。
