Relay catalysis using a gold(i) complex/Brønsted acid binary system for the synthesis of bezoxasiloles†
Abstract
A strategy for the synthesis of synthetically useful benzoxasilole derivatives by combining a gold(I) complex/Brønsted acid binary system and a temporary silicon tether method has been developed that involves relay catalytic cascade intramolecular allylation of alkynes by a gold(I) complex and addition of silanols to enones by a Brønsted acid.
