chlorides, with the monoanion of tosylmethyl isocyanide is described. The process gives entry to 3-(4-tosyl)imidazo[1,5-a][1,4]benzodiazepines, compounds which have not been described yet in the literature. These systems can be derivatized to the corresponding trisubstituted 1,4-benzodiazepines by alkylation or acylation of the imidazole ring. These new heterocyclic derivatives are potentially useful in
描述了用作亚胺酰氯的合成等效物的 1,4-苯二氮杂 N-亚硝基脒与甲苯磺酰基甲基异氰化物的单阴离子的反应。该方法得到 3-(4-甲苯磺酰基)咪唑并[1,5-a][1,4]苯二氮卓类化合物,这些化合物尚未在文献中描述。这些系统可以通过咪唑环的烷基化或酰化衍生为相应的三取代的 1,4-苯并二氮杂卓。这些新的杂环衍生物在药物化学领域具有潜在的用途。此外,咪达唑仑 3 具有良好的麻醉特性,可通过化合物 7a 的脱磺酰化一步轻松制备。
