aldehydes and formyl–substituted carboxylic acids, including ferrocene-based components, furnished a series of diastereomeric 6-aryl-substituted 5,6,8,9,14,14b-hexahydroindolo[2′,3′:3,4]pyrido[1-c]-quinazolines and 5,5b,17,18-tetrahydroindolo[2′,3′:3,4]pyrido[1,2-c]isoindolo[2,1-a]quinazolin-11-(15bH)-ones with the elements of central-, planar and conformational chirality. The relative configuration and
使用色胺和 l-色氨酸甲酯的 Pictet-Spengler 反应,随后还原硝基,然后与芳醛和甲酰基取代的羧酸(包括二茂铁基组分)进一步环缩合,提供了一系列非对映异构体 6-芳基-取代的 5,6,8,9,14,14b-六氢吲哚[2',3':3,4]吡啶并[1-c]-喹唑啉和 5,5b,17,18-四氢吲哚[2',3' :3,4]pyrido[1,2-c]isoindolo[2,1-a]quinazolin-11-(15bH)-ones,具有中心、平面和构象手性元素。新型多环吲哚衍生物的相对构型和构象由 1 H-和 13 C-NMR 方法确定,辅以可能的非对映异构体的比较 DFT 分析。具有确定的绝对构型“S”的五环甲酯之一的结构也通过单晶X射线衍射测量得到证实。在 DFT 建模结果的基础上,提出了对产物的特征取代基依赖性非对映选择性形成的解释。产品的初步体外细胞毒性分析显示对 PANC-1-、COLO-205-、A-2058
