Rh(III)-catalyzed oxidative C-H bond arylation with hydroquinones: sustainable synthesis of dibenzo[b,d]pyran-6-ones and benzo[d]naphtho[1,2-b]pyran-6-ones

Abstract

An efficient Rh(III)-catalyzed C-H bond arylation with phenol derivatives was developed for the direct and sustainable synthesis of dibenzo[b,d]pyran-6-ones and benzo[d]naphtho[1,2-b]pyran-6-ones. This reaction shows good substrate scope and excellent functional group compatibility and gives the products in good yields with excellent chemoselectivity.
