Flavanone and chromanone were also found to be facile substrates with the developed catalytic system. Mechanistic studies revealed the active catalytic species and the role of water in the reaction process as hydroxy and proton sources. Employing the developed method, total synthesis of cytosporone A was achieved in two steps and that of cytosporones B–C was achieved in three steps starting from resorcinol
已经在水性介质中开发了一种快速 Ir(III) 催化的芳基酮与重氮化 Meldrum 酸的羧甲基化反应。还发现黄烷酮和色满酮是具有开发催化体系的容易的底物。机理研究揭示了活性催化物质和水在反应过程中作为羟基和质子源的作用。采用所开发的方法,细胞孢子素 A 的全合成分两步完成,细胞孢子素 B-C 的全合成从间苯二酚开始分三步完成。
