Highly stereoselective ruthenium(II)-catalyzed direct C2-syn-alkenylation of indoles with alkynes

Org Lett. 2015 Mar 20;17(6):1349-52. doi: 10.1021/ol503618m. Epub 2015 Mar 6.

Abstract

A carboamide-directed ruthenium-catalyzed C2-hydroindolation of alkynes has been described. This transformation provides a rapid access to free (N-H) C2-syn-alkenylated indole derivatives with the assistance of copper(II) salts, in which the directing group is removed via a one-pot process.
