Abstract
A novel approach to the total synthesis of naturally occurring furanoflavones and furanochalcones is described. Angular and linear furanoflavones and furanochalcones have been prepared in just four steps, using economical reagents and simple reaction conditions. The key step of our approach is the formation of crucial precursors, 5-acetyl-4-hydroxy-coumarone and 5-acetyl-6-hydroxy-coumarone by Amberlyst 15-catalyzed cyclization of phenoxyacetal.
