The compounds with a quaternary α-aryl aldehyde skeleton are important units in organic chemistry. Previously, the aryl group and carbonyl group are introduced in a stepwise manner. Herein, a novel route is developed to construct the quaternary α-aryl aldehydes with gem-bis(boronates) as precursors, in which the two groups are installed simultaneously. The gem-bis(boronates) are readily available from
具有季α-芳基醛骨架的化合物是有机化学中的重要单元。先前,以逐步的方式引入芳基和羰基。在本文中,开发了一种新的途径来构建以宝石-双(硼酸酯)为前体的季α-芳基醛,其中两个基团同时安装。的宝石-双(硼酸酯)可容易地从酮; 结果,这种方法为生产具有广泛范围和合成方便性的季α-芳基醛提供了更通用的策略。
