Copper-catalyzed cycloaddition between hydrogen phosphonates and activated alkenes: synthesis of phosphonoisoquinolinediones†
Abstract
A new, general method for the synthesis of phosphonoisoquinolinediones has been achieved via copper-catalyzed phosphonation–cyclization of various methacryloylbenzamides with P(O)H compounds. This transformation allows the direct formation of a P–C bond and the construction of an isoquinolinedione ring in one reaction.
