acridones and their cyclo[b ]‐fused derivatives are efficiently constructed by a double annulation of o ‐enoyl arylisocyanides with α , β ‐unsaturated carbonyls under simple metal‐free condition. This protocol is general, efficient and practical, featuring the successive formation of two rings by a one‐pot domino transformation. A tandem process involing an isocyanide‐based [1+4] cycloaddition, an aminofuran‐based
在简单的无金属条件下,通过邻烯基芳基异氰酸酯与α,β-不饱和羰基的双环化,可以有效地构建各种各样的a烯及其环[ b ]稠合衍生物。该协议是通用,高效和实用的,其特点是通过一锅多米诺骨牌变换连续形成两个环。提出了将异氰酸酯基[1 + 4]环加成,氨基呋喃基分子内[4 + 2]环加成,开环和芳构化等串联过程。
