In this work, a new ynamide scaffold has been designed, synthesized and later applied in a gold-catalyzed cycloisomerization reaction to access pyrrole containing α,β-unsaturated ketones in low-to-moderate yields. Interestingly, the trans product has been obtained as a major isomer.
在这项工作中,设计、合成了一种新的 ynamide 支架,随后将其应用于金催化的环化异构化反应,以低至中等收率获得含有 α,β-不饱和酮的吡咯。有趣的是,反式产物已作为主要异构体获得。
