ylate with formamide gave 5-(1,4-benzodioxan-2-yl)thieno[2,3-d]pyrimidin-4(3H)-one which was treated with phosphoryl chloride in pyridine to obtain the corresponding 4-chloro derivative. The latter reacted with various primary and secondary amines to produce a series of new thieno[2,3-d]pyrimidines containing a pharmacophoric fragment at the 4-position. The reaction of 5-(1,4-benzodioxan-2-yl)-4-chlorothieno[2
摘要 先前合成的 2-氨基-4-(1,4-苯并二恶烷-2-基)噻吩-3-甲酸乙酯与甲酰胺环化得到 5-(1,4-苯并二恶烷-2-基)噻吩并[2,3- d ]pyrimidin-4(3 H )-one 在吡啶中用磷酰氯处理得到相应的4-氯衍生物。后者与各种伯胺和仲胺反应生成一系列新的噻吩并[2,3 - d ]嘧啶,在 4 位含有药效团片段。5-(1,4-benzodioxan-2-yl)-4-chlorothieno[2,3- d ]嘧啶与水合肼反应得到相应的4-肼基衍生物,该衍生物用甲酸环化为噻吩并[3,2 - e ][1,2,4]三唑并[1,5- c]嘧啶衍生物。研究了合成化合物的抗缺氧特性。
