Abstract

Abstract 3-Formyl-2H-chromenes which are readily accessible through an oxa-Michael reaction of salicylaldehydes and α, β-unsaturated aldehydes undergo a smooth decarbonylation reaction upon treatment with rhodium catalysts. With our method, a great variety of functionalized chromenes is accessible in a two-step sequence from salicylaldehydes.
