摘要

在此，我们公开了一种简单的单锅方法，利用叔丁醇钾从芳基乙烯基酮高效地进行区域和立体选择性合成 1,3,5-三芳基环己烷。所开发的方案可以以良好到极佳的收率合成各种对称取代的环己烷。主要产物 2 还可以在酸催化下方便地转化为产物 3（均为赤道型）。该方案具有良好的底物范围和官能团兼容性。

Regio- and Stereoselective Construction of 1,3,5-Triaroylcyclohexanes via KOtBu-Mediated Cyclotrimerization of Aryl Vinyl Ketones

Herein, we disclose a simple one-pot method for an efficient regio- and stereoselective synthesis of 1,3,5-triaroylcyclohexanes from aryl vinyl ketones using potassium tert-butoxide. The developed protocol allows the construction of various symmetrically substituted cyclohexanes in good to excellent yields. The major product 2 also can be converted to the product 3 (all equatorial) conveniently by acid catalysis. This protocol features a good substrate scope and functional group compatibility.
