A bicyclic aromatic compound formed by fusing benzene to a pyran ring (a six-membered ring containing oxygen), used in natural product chemistry and synthesis.
From benzo- (benzene) + pyran (from py- fire + -an, a six-membered heterocycle). Named in early 20th-century heterocyclic chemistry.
Benzopyran is the basic skeleton of chromans and coumarins, which are found in plants—flavonoids (plant pigments that give berries their color) are all built on benzopyran frameworks, making this simple molecule surprisingly important to plant life.
