3,3-Diphenyl-3H-naphtho[2,1-b]pyran Chemical Properties,Usage,Production

Uses

3,3-Diphenyl-3H-naphtho[2,1-b]pyran is a useful research chemical compound used in the preparation and photochromism of naphthopyrans, pyranoquinolines, pyranoquinazolines, and pyranoquinoxalines.

Synthesis

The building of the 3,3-diphenyl-3H-naphtho[2,1-b]pyrans can be achieved by a 'one-pot reaction' starting from a suitable naphthol and 1,1-diphenyl-2-yn-1-ol^[1]. This condensation reaction takes place in an apolar solvent (toluene, CH2Cl2) under acid catalysis.
