of nitroalkenes with enol ethers followed by reductive ring contraction of the resulting cyclic nitronates provides a new access to polysubstituted NH pyrroles. Unlike conventional synthetic routes (Barton-Zard, Knorr, Hantzsch, Van Leusen pyrrole syntheses), this strategy affords NH pyrroles that do not necessarily contain a EWG group in the ring.
硝基烯烃与烯醇醚的[4+2]-环加成,随后所得环状硝基化合物的还原环收缩提供了获得多取代NH吡咯的新途径。与传统的合成路线(Barton-Zard、Knorr、Hantzsch、Van Leusen 吡咯合成)不同,该策略提供的 NH 吡咯在环中不一定包含 EWG 基团。
