Meeting the challenge of intermolecular gold(I)-catalyzed cycloadditions of alkynes and allenes

Abstract

The development of gold(I)-catalyzed intermolecular carbo-and hetero-cycloadditions of alkynes and allenes has been more challenging than their intramolecular counterparts. Here we review, with a mechanistic perspective, the most fundamental intermolecular cycloadditions of alkynes and allenes with alkenes.
