Advancement in synthetic strategies of bisdimedones: Two decades study.

Bisdimedones have emerged as an important and versatile moiety in the field of synthetic and medicinal chemistry. It is screened as a precursor for the synthesis of several heterocycles such as acridinediones, xanthenediones, thioxanthenes, and benzopyrans that exhibited immense pharmacological as well as industrial applications. Its extensive characteristics have attracted the scientists to develop various protocols for the synthesis of bisdimedones and their derivatives from the reaction of dimedone with several aldehydes under different environmental conditions using various types of catalysts. This review encapsulates the recent progress in the synthesis of bisdimedone derivatives under several reaction protocols such as the use of nanoparticles, ionic liquids, metal salts, simple organic compounds, and catalyst‐free conditions, and so forth in the last 20 years.
