  Ketene Addition on Thienoanellated Thiazines and Thiazepines with Subsequent Ring Enlargement Reaction to Thieno[2,3-b][1,4]thiazocines and Thieno[2,3-b][1,4]thiazonines

  摘要：

  Reaction of alkylthiothieno[2,3-b][1,4]thiazine derivatives or alkylthiothieno[2,3-b][1,4]thiazepine derivatives (4, 5, 12, 16, and 24) with substituted acetyl chlorides in the presence of triethylamine led to azeto[1,2-d]thieno[2,3-b][1,4]thiazine derivatives and azeto[1,2-d]thieno[2,3-b][1,4]thiazepine derivatives. Some of them were ring opened by treatment with trifluoroacetic acid to give the thieno[2,3-b][1,4]thiazocine derivatives (27 - 30) and the thieno[2,3-b][1,4]thiazonine derivative (32), respectively. 6-Ethyl-1H-thieno[2,3-b][1,4]thiazine-2(3H)-thione (13), after reaction with alpha-chlorophenylacetyl chloride and triethylamine, afforded the thiazolo[2,3-b][1,4]thiazine derivative (34).
