Abstract:

The redox reaction of 2-trifluoromethylchromones with ethyl mercaptoacetate in the presence of triethylamine results in the formation of 1,2-dihydrothieno{[}2,3-c]chromen-4-ones and diethyl 3,4-dithiadipate in high yields. Oxidation of the first compounds with nitrogen dioxide gave 1,2-dihydrothieno{[}2,3-c]chromen-3,4-diones which were converted into thieno{[}2,3-c]chromen-4-ones. (C) 2003 Elsevier Science Ltd.
