Synthesis of 3‐substituted‐4‐phenyl‐2‐thioxo‐1,2,3,4,5,6,7,8‐octahydrobenzo[4,5]thieno[2,3‐á]pyrimidines
摘要:
The reactions between 3-benzoyl-2-isothiocyanato-4,5,6,7-tetrahydrobenzo[ b ]thiophene and hydrazine or primary amines have been studied. The products obtained were identified as derivatives of 4-phenyl-2-thioxo-2,3,5,6,7,8-hexahydrobenzo[4,5]thieno[2,3- d ]pyrimidine. Their easy reduction with sodium borohydride provided a useful method for the synthesis of 3-substituted-4-phenyl-2-thioxo-1,2,3,4,5,6,7,8-octahydrobenzo[4,5]thieno[2,3- d ]pyrimidines. Both kind of compounds were evaluated as potential analgesic, anti-inflammatory and anti-arthritic agents.
