摘要 Photo-irradiation of 2-（5-methylthiophen-2-yl）-3-[（naphthalen-2-yl）methoxy]-4H-chromen-4-ones yielded the fascinating angular tetracyclic products via cyclization involving both 2-thienyl ring and naphthylmethoxy group via 1,4-biradical generated in the Norrish type-II process. The stereochemical dispositions of the products were determined by MM2 energy minimized programme and spectroscopic analysis.
