ascertained using chiroptical spectroscopic methods and/or single-crystal XRD data. A combination of different reaction strategies delivering a diverse matrix of fused heterocyclic ring systems is presented. The pyrrolo[2,1-a]isoquinoline alkaloid (+)-crispine A possesses a wide range of pharmacological activities including antidepressant, antiplatelet, antileukemic, and anticancer activities. The analogues
从热带植物中大量分离的天然产物 (2 S ,3 S )- 和 (2 S ,3 R )-3-羟基-5-氧代四氢呋喃-2,3-二羧酸(1和2)的多功能性来源,已通过构建 3-取代和 3,4-二取代手性吡咯烷-2,5-二酮证明。手性吡咯烷-2,5-二酮的绝对构型已使用手性光谱方法和/或单晶 XRD 数据确定。提出了提供不同稠合杂环系统矩阵的不同反应策略的组合。吡咯[2,1- a]异喹啉生物碱 (+)-crispine A 具有广泛的药理活性,包括抗抑郁、抗血小板、抗白血病和抗癌活性。indolizino[8,7- b ]indole 生物碱 (+)- 和 (-)-harmicine 的类似物显示出很强的抗利什曼原虫、镇痛、PDE5 抑制、抗疟和抗病毒活性。双环呋喃[2,3- b ]吡咯骨架存在于许多天然产物中。因此,相对便宜的、天然存在的手性 2-羟基柠檬酸内酯作为 chirons 的独特性已通
