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
研究了3-苯甲酰基-2-异硫氰酸根合4,5,6,7-四氢苯并[ b ]噻吩与肼或伯胺的反应。鉴定出的产物为4-苯基-2-硫代氧代2,3,5,6,7,8-六氢苯并[4,5]噻吩并[2,3- d ]嘧啶的衍生物。它们易于用硼氢化钠还原,为合成3-取代的4-苯基-2-硫代-1,2,3,4,5,6,7,8-八氢苯并[4,5] thieno [ 2,3- d ]嘧啶。两种化合物均被评估为潜在的镇痛药,抗炎药和抗关节炎药。
