ABSTRACT An eco-friendly synthesis of pyrano[3,2-c]chromen-5(4H)-one derivatives was conducted by the condensation of 4-hydroxycoumarins, aromatic aldehydes, and acetophenones. Clean profile, excellent yield, ambient temperature, and use of visible light intensity instead of catalyst are the attractive features of this method. GRAPHICAL ABSTRACT
