we disclose a three‐step “[2 + n]” annulation method for the transformation of cyclic ketones to fused enimines and enones. The method relies on the Suzuki coupling reaction and the amide reductive alkenylation reaction. A series of fused bicyclic (6/6, 6/7, 8/7) and tricyclic (6/6/6; 6/6/7, 6/5/7) ring systems bearing an α,β‐enimine or an α,β‐enone functionality have been synthetized in good overall
功能化多环结构的有效构建是有机合成中的重要目标。本文中,我们公开了一种三步“ [2 + n ]”环化方法,用于将环酮转化为稠合的
亚胺和烯酮。该方法依赖于Suzuki偶联反应和酰胺还原性烯基化反应。一系列稠合的双环(6/6,6/7,8/7)和
三环(6/6/6; 6/6/7,6/5/7)环系统,带有α,β-
亚胺或已成功合成了α,β-烯酮官能团。
