Amides have been one of the most popular compounds in organic chemistry. There are plenty of important applications in many fields such as medicinal chemistry, biochemistry and polymer synthesis. Highly efficient synthesis of amides has become a hot topic in recent years. In this review, the application of transition metal catalysis and small molecule organocatalysis in the synthesis of amides in the last few years is briefly summarized, and the prospects of the synthesis of amides are also discussed.
