High atomic utilization conversion of ethers into furancarbaldehydes via an ether oxidation iminium-ion activation cascade strategy

Abstract

A novel organocatalytic one-pot cascade ether oxidation iminium-ion activation strategy for the synthesis of naphtho[2,1-b]furan-1-carbaldehyde and benzofuran-3-carbaldehyde from high atomic utilization transformation of aryl allyl ethers has been developed. Its synthetic application will provide a new ether oxidation iminium-ion activation cascade tool for the efficient synthesis of complex molecules.
