Organocatalytic cascade reactions for multi-functionalized chiral cyclic ethers through vinylidene ortho-quinone methides

Chem Commun (Camb). 2021 Oct 28;57(86):11334-11337. doi: 10.1039/d1cc05340j.

Abstract

An organocatalytic approach to installing various alcohols into the carbonyl of α,β-unsaturated ketones mediated by VQM intermediates was achieved, followed by dearomatization to provide the stereo-defined cyclic ethers via a cascade process. Along with the transformations, this strategy affords efficient access to the underexplored chiral cyclic ether chemospace.
