12-hexahydro-5 H -imidazo[1′,2′:1,2]pyrimido[4,3- a ]isoquinolines representing new types of 8,13,15-triazasteroids is described. The tetracyclic title compounds were prepared from 4-(2-hydroxyalkylamino)tetrahydro-2 H -pyrimidoisoquinolines, which furnish after conversion to the corresponding bromoalkylamino compounds and base-catalyzed intramolecular nucleophilic displacement cyclization of the latter
1,2,6,10b,11,12-hexahydro-5 H- 咪唑并[1',2':1,2]嘧啶基[4,3- a ]异喹啉的合成代表了8,13,15的新类型描述了三氮杂甾体。由4-(2-羟基烷基氨基)四氢-2 H 制备四环标题化合物 -pyrimidoisoquinolines,在转化为相应的溴代烷基氨基化合物后,经碱催化的分子内亲核取代环化反应形成所需的带有芳香环A的1-取代的8,13,15-三氮甾类化合物。同核和异核相关1D和2D NMR实验的基础。标题化合物代表在角鲨烯经酶促转化为麦角固醇过程中形成的甾族底物的选定高能中间体(HEI)的三氮杂类似物,并被设计用作HEI的抑制模拟物和潜在的抗真菌药。
