The reaction of N-chloroacetyl derivatives 6-10 with morpholine yielded N-morpholin-1-yl acetyl derivatives 11-15 , which were subjected to Thorpe-Zieler cyclization with sodium tert -butoxide to produce the corresponding condensed pyridin-2(1H)-onederivatives 16-20 . Treatment of compounds 1 , 6-10 with either malononitrile or p -chlorobenzylidinemalononitrile in presence of triethylamine, afforded

Regarding to the importance of thieno[2,3‐b]thiophens and isothiocyanaetes reactiveties in the physical, chemical and pharmaceutical fields, this study has been undertaken to prepare the target compound 5‐cyano‐2‐carbethoxythieno[2,3‐b]thiophenyl‐3,4‐diisothiocyanates via a safe method. The formed isothiocyanates derivative was reacted with aromatic amines, acid hydrazied and some active methylene
