preparation of ketones from carboxylate anions is greatly limited by the required use of organolithium reagents or activated acyl sources that need to be independently prepared. Herein, a specific magnesium amide additive is used to activate and control the addition of more tolerant Grignard reagents to carboxylate anions. This strategy enables the modular synthesis of ketones from CO2 and the preparation
由羧酸根阴离子直接制备酮受到有机锂试剂或需要独立制备的活化酰基源的使用的极大限制。在本文中,使用特定的酰胺化镁添加剂来激活和控制更具耐受性的格利雅试剂的添加以使阴离子羧酸化。这种策略可以在一次操作中从CO 2模块化合成酮,并制备同位素标记的药物结构单元。
