Thionation of chalcone and aurone derivatives by Lawesson's reagent

The reaction of Lawesson's reagent (LR 5) with chalcones (4a-h) and aurones (12a-h) proceeds in refluxing toluene to give the respective benzofuranylprop-2-en-1-thiones (8a-h) and benzodifuran-3-thiones (13a-h). Correct elemental analyses and spectroscopi

Photochemical reaction of phenanthrenequinone with some new aurones derived from khellin and visnagin

Phenanthrenequinone 2 and aurones 5a-h are potentially capable of undergoing an interesting photochemical reaction leading to the formation of the adducts 6a-h. The structures of the 1,4-dioxine derivatives 6a-h were firmly established on the basis of analytical data and spectroscopic evidences.
