Abstract

Ring transformation reactions using 2H-pyran-2-ones as valuable synthetic precursor with several nucleophiles for designing numerous interesting scaffolds is a growing field in synthetic organic chemistry. 2H-Pyran-2-ones has tendency to act as very good Michael acceptor and hence functions as good electrophile. The scope of 2H-pyran-2-ones has been explored for the synthesis of various molecules owning significant biological importance. Additionally, their synthetic potential has been discovered for the construction of interesting photophysically active molecules. From this point of view, the development of simple and environmental benign ring transformation strategy is a dynamic research field until today. This short review describes an overview of the most recent advances in ring transformation of functionalized 2H-pyran-2-ones into valuable aromatic scaffolds like functionalized benzenes, N-heterocycles and fused ring systems.
