摘要

通过一次操作同时实现了炔酮的环化反应和氢化磺酰化反应。在碳酸铯的介导下，不同的 S-（α-羟基芳基）芳基硫代磺酸盐与各种炔酮发生反应，生成功能化的乙烯基砜，E-选择性收率为 37%-83%。同时，还生成了多种苯并氧硫杂蒽，产率为 42%-97%。

Synthesis of Vinyl Sulfones and Benzoxathiins via Base-Catalyzed Reactions of o-Hydroxyaryl Thiosulfonates and Ynones

The cyclization reaction and hydrosulfonylation reaction of ynones have been simultaneously realized through a single operation. Under the mediation of cesium carbonate, different S-(α-hydroxyaryl) aryl thiosulfonates reacted with various ynones to produce functionalized vinyl sulfones in 37%-83% yields with E-selectivity. At the same time, a variety of benzoxathiins were formed in 42%-97% yields.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
