One-pot synthesis of novel 2,3-dihydro-1H-indazoles

Abstract

A copper(I)-mediated one-pot synthesis of 2,3-dihydro-1H-indazole heterocycles has been developed. This synthetic route provides the desired indazoles in moderate to good yields (55%-72%) which are substantially better than those achievable with an alternative two-step reaction sequence. The reaction is tolerant of functionality on the aromatic ring. © 2011 by the authors; licensee MDPI, Basel, Switzerland.
