Dearomative oxyphosphorylation of indoles enables facile access to 2,2-disubstituted indolin-3-ones

Org Biomol Chem. 2022 Jul 27;20(29):5721-5725. doi: 10.1039/d2ob01063a.

Abstract

A highly efficient oxidative dearomatization of indoles with H-phosphorus oxides in the presence of TEMPO oxoammonium salt has been demonstrated. Through the intramolecular oxidative dearomatization of indoles and subsequent intermolecular nucleophilic addition with phosphorus nucleophile, a variety of structurally diverse arylphosphoryl and alkylphosphoryl indolin-3-ones were obtained in good yields with a broad substrate scope and high functional-group compatibility.
