Copper(I)‐Catalyzed Proto/Carboboration of Enyne Boronates for the Synthesis of Densely Substituted Diene Diboronates

A copper‐catalyzed carbo‐/protoboration of boryl enynes is disclosed, providing access to an array of penta‐ and hexasubstituted diboryl dienes in a chemo‐, regio‐ and stereoselective manner. All six positions of the dienes can be manipulated using this methodology. The hexasubstituted diene boronates adopt a skew conformation. An iterative Suzuki coupling of the products provided highly conjugated trienes and tetraenes.

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.
