Mono-, Bis- and Tris (Thio) Substituted Nitrobutadienes from 2-Nitrodiene with 7-Mercapto-4-Methyl Coumarin and N,S-Substituted Dienes from Mono(Thio)-Substituted Dienes with Amines

Abstract

Thiosubstituted nitrodien compounds 3a and 4a were prepared by mixing compound 1 with thiol 2a. 1 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 CH₂Cl₂. 7a–h and 9a–d were obtained by the reactions of 6a–h and 8a–d with compound 3a.
