for the synthesis of 8-oxo-10-sulfanylpyrido[4',3':4,5]thieno[3,2-d]pyrimidines, annulated with pyran, cyclohexane, or cyclopentane rings. The alkylation of these compounds in aqueous DMF solution of KOH at room temperature was shown to proceed regioselectively and led to the formation of S-substituted products. Amino- and alkoxy-substituted derivatives of tetracyclic thieno[3,2-d]pyrimidines were synthesized
我们提出了一步法合成8-氧代-10-磺酰胺基吡啶并[4',3':4,5]噻吩并[3,2- d ]嘧啶,并用吡喃,环己烷或环戊烷环进行环化。在室温下,在KOH的DMF水溶液中这些化合物的烷基化显示出区域选择性地进行,并导致形成S-取代的产物。合成了四环噻吩并[3,2- d ]嘧啶的氨基和烷氧基取代衍生物。在革兰氏阳性葡萄球菌和革兰氏阴性棒上研究了所得化合物的抗菌活性。
