cycloaddition with tethered alkenes to provide stereochemically complex N-heterocyclic scaffolds. These processes rely upon the generation and trapping of rhodacyclopentanone intermediates, which arise by regioselective, Cbz-directed insertion of Rh and CO into one of the two proximal aminocyclopropane C-C bonds. For cyclizations using cationic Rh(I)-systems, synthetic and mechanistic studies indicate that rhodacyclopentanone
在暴露于中性或阳离子 Rh(I)-催化剂体系后,氨基取代的环丙烷与系链烯烃发生羰基化环加成反应,以提供立体化学复杂的 N-杂环支架。这些过程依赖于环戊酮中间体的产生和捕获,其通过区域选择性、Cbz 定向将 Rh 和 CO 插入到两个近端氨基环丙烷 CC 键之一中而产生。对于使用阳离子 Rh(I) 系统的环化,合成和机理研究表明,环戊酮的形成是可逆的,并且烯烃插入步骤决定了产物的非对映选择性。这种机制有助于对烯烃系链上的取代基进行高水平的立体控制。
The application relates to 2-imino-hexahydropyrimidin-4-one derivatives of formula (I) which are potent inhibitors of the growth and propagation of the Plasmodium falciparum parasite in human blood and thus useful for the treatment of malaria.
