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。

triazolo[1,5-c]pyrimidines were developed. The Dimroth rearrangement of these systems was studied. Pharmacological investigation of the synthesized compounds was conducted in known tests, such as antagonism with subcutaneous administration of corazole and the open-field test. The rotating rod method was used to assess the neurotoxicity. Neurotropic properties were found in many derivatives of triazolopyrimidine
