A facile one-step synthetic approach to dihydrofuro[3,2-c]chromenones and furo[3,2-c]chromenones by the reaction of methyl enol ethers with 4-hydroxy coumarin in a metal-free condition is presented. Dihydrofuro[3,2-c]chromenones and furo[3,2-c]chromenones were selectively obtained by controlling the stoichiometry of boron trifluoride diethyl etherate (BF 3.Et 2O). An unexpected aryl group migration followed by aromatization of furan moiety leading to a variety of furo[3,2-c]chromenone derivatives in good yields is reported. © 2022 Georg Thieme Verlag.
