✦ Synopsis

A Facile Synthesis of Angularly-Fused 3,4,4a,10b-Tetrahydro-2H,5Hpyrano(3,2-c) (1)benzopyrans by the One-Pot Condensation Between Salicylaldehydes and Unsaturated Alcohols.

-An expedient method for the stereoselective synthesis of trans-fused tetrahydropyranobenzopyrans (III) by reacting salicylaldehydes with 4-alkenols is established. - (INOUE,
