Thiosubstituted nitrodien compounds 3a and 4a were prepared by mixing compound 1 with thiol 2a. I gave 5a by the reaction with coumarin derivative 2a in, EtOH containing sodium. hydroxide. Mono(thio)substituted diene compound 3 reacted with 10 and 12 and yielded 11 and 13 in CH2O2. 7a-h and 9a-d were obtained try the reactions of 6a-h and 8a-d with coinpound 3a.
