  Antimalarial Properties of Simplified Kalihinol Analogues

  摘要：

  Several kalihinol natural products, members of the broader isocyanoterpene family of antimalarial agents, are potent inhibitors of Plasmodium falciparum, the agent of the most severe form of human malaria. Our previous total synthesis of kalihinol B provided a blueprint to generate many analogues within this family, some as complex as the natural product and some much simplified and easier to access. Each analogue was tested for blood-stage antimalarial activity using both drug-sensitive and -resistant P. falciparum strains. Many considerably simpler analogues of the kalihinols retained potent activity, as did a compound with a different decalin scaffold made in only three steps from sclareolide. Finally, one representative compound showed reasonable stability toward microsomal metabolism, suggesting that the isonitrile functional group that is critical for activity is not an inherent liability in these compounds.

  cross‐conjugated dienone structural motif of 1 was forged by an aldol reaction/dehydration sequence from key building blocks enone 13 and aldehyde 14, whose lone stereocenters were generated by an asymmetric Tsuji–Trost reaction and an asymmetric Mukaiyama aldol reaction, respectively. During this program, a substituent‐governed regioselectivity pattern for the Rh‐catalyzed C−H functionalization of cyclopentenes

  Δ的总合成12 -前列腺素Ĵ 3（Δ 12 -PGJ 3，1），所报告的白血病干细胞消融器，通过若干战略和战术进行说明。关键的共轭烯酮13和醛14的醛醇缩合反应/脱水序列伪造了1的标志性交叉共轭二烯酮结构基序。，其单独的立体中心分别由不对称的Tsuji-Trost反应和不对称的Mukaiyama aldol反应产生。在该程序中，发现了用于Rh催化的环戊烯和相关烯烃的CH官能化的取代基控制的区域选择性模式。1的合成从最初的策略发展到最终的简化流程，这是通过改进片段13和14的结构，探索迄今未充分利用的手性内酯合成子57的化学性质以及环戊烯酮中间体的非对映选择性烷基化来进行的。 。所描述的化学设置了大规模生产Δ的阶段12 -PGJ3并设计类似物用于进一步的生物学和药理研究。

  A highly efficient regio- and enantioselective monohydrogenation of 1,4-dienes has been realized using an iridium catalyst with a chiral N,P-ligand under mild conditions. The substrate scope was studied and included both unfunctionalized as well as functionalized substituents on the meta- or para-position. Substrates having substituents with functionalities such as silyl protected alcohols or ketals
