Recent Advances in Stetter Reaction and Related Chemistry: An update.

The Stetter reaction is actually a special C−C bond forming reaction through a 1,4‐addition reaction in the presence of nucleophilic catalyst. It involves a reaction between aldehydes and Michael acceptors catalyzed by N‐heterocyclic carbenes (NHC's) leading to preparation of 1,4‐dicarbonyl compounds via carbon‐carbon bond formation. It offers a powerful approach to access 1,4‐dicarbonyl compounds which are significant starting materials and intermediates in the synthesis of several heterocyclic systems, and bioactive heterocyclic framework which are present in natural products. In this review we try to underscore the recent advances in Stetter reaction and its applications from 2015 till date. Notably, we focused on the applications of Stetter reaction in the synthesis of various heterocyclic systems and total synthesis of natural products, which have largely been overlooked, previously.
