Abstract Pyrans are a class of six‐membered heterocyclic rings containing five carbon atoms and one oxygen atom. They non‐aromatic in nature, bearing two double bonds the ring. The bond position distinguishes pyran isomers, namely, 2 H ‐pyran 4 ‐pyran. When saturated sp 3 is located next to an atom, it known as ‐pyran, when at 4‐position with respect In 1962, by thermal breakdown 2‐acetoxy‐3,4‐dihydro‐2 ‐pyrans were produced for first time, their characteristics explored. Numerous synthetic methods have been disclosed over time owing broad applications diverse fields, mainly drug design, pharmaceuticals, material science. this review, we highlight recent advancements toward substituted 4‐pyranone, 2‐pyranones, focusing on reports published from 2019 till date, which play important roles both organic synthesis types functional molecules.
