More rings for your rhodium: Rhodium‐catalyzed intermolecularalkynehydroacylations deliver γ‐hydroxy‐α,β‐enones, which can be cyclized in situ to deliver di‐ and trisubstituted furans. Functionalization of the intermediates using Heck chemistry allows the formation of regioisomeric furans. The use of an alternative RhI catalyst delivers 1,4‐dicarbonyl compounds and hence pyrroles, thiophenes, and

ynamides containing an o-(methylthio)aryl group resulted in the one-pot formation of biologically important benzo[b]thiophenes. Compared with ynamide activation methods that use strong Brønsted acids or expensive transition metals, this protocol is mild and economical. Due to these merits, various functionalized 2-amidobenzo[b]thiophenes were furnished in a convenient way.
硅胶促进或溶剂促进含有邻-(甲硫基)芳基的ynamides的质子分子内环化导致一锅法形成生物学上重要的苯并[ b ]噻吩。与使用强布朗斯台德酸或昂贵的过渡金属的 ynamide 活化方法相比,该协议温和且经济。由于这些优点,各种官能化的2-氨基苯并[ b ]噻吩以方便的方式提供。
