General description
6-Methylchromone hydrate is a chromone derivative. Chromones are cyclic compounds containing nine carbon atoms with sp2 hybridization. They are commonly referred as 1,4-benzapyranes or γ-benzopyrones.
Application
6-Methylchromone may be employed as activated alkene in the methanolic trimethylamine or sodium methoxide catalyzed Baylis-Hillman coupling reaction with aromatic and aliphatic aldehydes.

Polyhaloalkyl-substituted chromones, gamma-pyrones, and beta-furanones react with salicylaldehydes in the presence of piperidine to give a wide variety of fused 2H-chromenes in good yields. This novel annulation reaction presumably proceeds by a tandem intermolecular oxa-Michael addition and subsequent intramolecular Mannich
