摘要

通过炔基芳基酮与磺酰硒酸盐的级联硒化/环化反应,可以很容易地制备出各种 2-取代的 3-硒基色烯酮。这种转化在无金属条件下进行,不需要额外的氧化剂。它还具有广泛的官能团耐受性和可扩展性。

Metal-Free Synthesis of Selanyl-Substituted Chromenones via Selanylation­/Cyclization of Alkynyl Aryl Ketones

Metal-Free Synthesis of Selanyl-Substituted Chromenones via Selanylation­/Cyclization of Alkynyl Aryl Ketones

A variety of 2-substituted 3-selanyl-chromenones are readily prepared through a cascade selanylation/cyclization of alkynyl aryl ketones with sulfonoselenoates. This transformation is performed under metal-free conditions and does not require an additional oxidant. It also has the advantage of broad functional group tolerance and scalability.
