(Boc-anhydride) to provide the corresponding tert-butyl aryl acetates, di-tert-butyl aryl malonates, unsymmetrical aryl malonates and tert-butyl benzoates in high yields. This reaction represents another useful way to prepare a variety of tert-butyl carboxylates and highlights the synthetic utility of di-tert-butyl dicarbonate as a versatile carboxylating reagent.
通过非亲核碱(LDA)生成的碳亲核试剂被有效捕集与二-叔丁基二碳酸酯(Boc-酸酐),以提供相应的叔丁基的芳基乙酸酯,二-叔丁基的芳基丙二酸酯,芳不对称丙二和叔高产率的苯甲酸丁酯。该反应表示准备各种的另一种有用的方式叔丁基羧酸盐和二-亮点的合成效用叔丁基二碳酸酯作为多功能羧试剂。
