Graphene Oxide Promotes Site-Selective Allylic Alkylation of Thiophenes with Alcohols

Org Lett. 2018 Jun 15;20(12):3705-3709. doi: 10.1021/acs.orglett.8b01531. Epub 2018 Jun 4.

Abstract

The graphene oxide (GO) assisted allylic alkylation of thiophenes with alcohols is presented. Mild reaction conditions and a low GO loading enabled the isolation of a range of densely functionalized thienyl and bithienyl compounds in moderate to high yields (up to 90%). The cooperative action of the Brønsted acidity, epoxide moieties, and π-surface of the 2D-promoter is highlighted as crucial in the reaction course of the present Friedel-Crafts-type protocol.
