dehydrogenase type-3 inhibitor, is described. These compounds were synthesized via construction of their 3,4-dihydro-2H-benzo[b][1,4]oxazine, dibenzodiazepine, and dibenzazocine skeletons, respectively, using the reductive ring-expansion reaction of the corresponding bicyclic or tricyclic oximes with diisobutylaluminum hydride.
描述了三种临床候选药物的合成:人尿酸盐转运蛋白-1抑制剂,精氨酸加压素拮抗剂和17β-羟基类固醇脱氢酶3型抑制剂。使用相应的双环或三环肟的还原环扩环反应,分别通过构建3,4-二氢-2H-苯并[b] [1,4]恶嗪,二苯并二氮杂卓和二苯甲唑嗪骨架来合成这些化合物。二异丁基氢化铝。
