Starting from 3-benzoyl-5-formyl-indolizine, 3-benzoyl-5-(2'2'-diacetylethenyl)-indolizines and analogs were obtained by the 〓mediated aldol condensation or Wittig reaction. These compounds,promoted by low-valent titanium, gave highly functionlizedcycl[3,2,2]azine derivatives. The coupling reaction proceeded betweenthe carbonyl group and the carbon-carbon double bond, a rare example inMcMurry reaction.

我们以3-苯甲酰基-5-甲酰基中氮茚为原料，通过三碘化钐促进的aldol反应和Wittig反应制备了3-羰基-5-羰基乙烯基中氮茚，随后经低价钛还原偶联，没有生成正常的分子内羰基-羰基偶联产物，而是得到反常的羰基与α，β-不饱羰基的双键偶联产物，较高收率地得到了含多官能团的CycI[3，2，2]azine衍生物。

Following developments in electrical theories such as Coulomb's law , which showed that positive and negative charges attract, analogs in human life were developed, such as "opposites attract."

随着电学理论的发展，例如库仑定律的提出表明异种电荷相互吸引，类似的概念在人类生活中也被提出，例如"异性相吸"。

In some cases, its epimer 4 was also obtained. 22 compounds were synthesized, among them 18 were new.3. Using the intramolecular Pictet-Spengler reaction to form the pentacyclic skeleton of Et-743, the byproducts 25 were obtained under various conditions. The structures of them were determined to be 1, 2-dihydro-isoquinoline compounds, and the mechanism of the reaction was proposed.B. The synthesis of the analogs of Et-743Because of the failure of removing the protective groups in compounds 14, the synthetic strategy was adjusted.

对于苄基保护的羟基化合物13a，顺利得到化合物30，然后与不同的羧酸反应得到18个酯化合物33-50；对于苄氧羰基保护的氨基化合物13b，由于脱除保护基的化合物31在空气中不稳定，所以我们采取不经分离纯化，直接与羧酸反应得到酰胺化合物53-62，然后再分别对其C-21位的羰基进行还原氰基化，得到10个酰胺目标化合物63-72，另外，我们还对羟基转化为氨基的反应进行了探索。3。
