Abstract

AbstractHeterocycles are important compounds existed in diverse advanced chemicals, functional materials, bioactive molecules and natural products. Different strategies through transition metal‐catalyzed alkyne cyclization have been developed to synthesize various heterocycles. The merger of alkyne cyclization and metal nanoparticle catalysis has emerged as an important approach to diverse heterocycles. By using different kinds of metal nanoparticle catalysts, such as gold, silver, copper and palladium nanoparticles, a number of heterocycles are prepared with high yield and selectivity in a green, sustainable and highly efficient manner. This review summarizes and discusses recent achievements in metal nanoparticle‐catalyzed alkyne cyclization for the synthesis of heterocycles.
