  • A divergent strategy for synthesis of the tetrahydroisoquinoline alkaloids renieramycin G and a lemonomycin analog
    作者:Philip Magnus、Kenneth S. Matthews
    DOI:10.1016/j.tet.2012.02.043
    日期:2012.8
    A divergent synthesis to the tetrahydroisoquinoline alkaloids (±)-renieramycin G and (±)-lemonomycinone amide is reported. A strategy was developed that allowed access to both the diazabicyclo[3.3.1]nonane and diazabicyclo[3.2.1]octane ring systems of the respective targets from a common advanced intermediate. The high diastereoselectivity observed throughout the synthesis is controlled by the first
    报道了四氢异喹啉生物碱(±)-雷尼霉素G和(±)-柠檬霉素酰胺的不同合成。开发了一种策略,该策略允许从同一高级中间体访问各自靶标的二氮杂双环[3.3.1]壬烷和二氮杂双环[3.2.1]辛烷环系统。在整个合成过程中观察到的高非对映选择性是由未活化异喹啉烷基化形成的第一个立体中心控制的。的主要结果包括异喹啉的不含钯的拉洛克条件下的合成,非对映选择性离子氢化条件设置1,3-顺-tetrahydroisoquinoline架构中,高度非对映reprotonation,和亲硫的路易斯酸催化的5-内切-三角函数Ñ-酰基亚胺离子甲硅烷基烯醇醚环化。对四氢异喹啉生物碱的这种发散方法为该天然产物家族中进一步的结构多样性提供了另一种策略。

  • Catalytic Asymmetric Synthesis of Quaternary Carbon Centers. Exploratory Studies of Intramolecular Heck Reactions of (<i>Z</i>)-α,β-Unsaturated Anilides and Mechanistic Investigations of Asymmetric Heck Reactions Proceeding via Neutral Intermediates

    日期:1998.7.1
    Intramolecular Heck reactions of seven (Z)-α,β-unsaturated 2-iodoanilides catalyzed by Pd−BINAP were surveyed using two reaction conditions: (1) silver-promoted cyclizations in the presence of 2 equiv of Ag3PO4 and (2) base-promoted cyclizations in the presence of 4 equiv of 1,2,2,6,6-pentamethylpiperidine (PMP). A comparison of these results with the outcome of the corresponding intramolecular Heck reactions

    Crude coumarin constituents of Peucedanum praeruptorum Duun. including praeruptorin A (=Pd-Ia)(2) and B (=Pd-II)(11) had an antagonistic effect on a specific platelet activating factor (PAF) in the platelet aggregation induced by several aggregating agents. This provides a new class of PAF antagonists. Studies of the structure-activity relationship with khellactone (1) derivatives and PAF antagonistic activity indicate that the cis isomers of 1 at the C-3' and C-4' positions are more favorable than trans isomers, and the acyl moiety at the C-3' position of 1 requires an appropriate molecular size.
    Peucedanum praeruptorum Duun. 的粗类香豆素成分,包括 praeruptorin A (=Pd-Ia)(2) 和 B (=Pd-II)(11),对由多个聚集剂诱导的血小板聚集中一种特定的血小板激活因子 (PAF) 产生了拮抗作用。这提供了一类新的 PAF 拮抗剂。对 khellactone (1) 衍生物与 PAF 拮抗活性之间的结构-活性关系研究表明,1 在 C-3' 和 C-4' 位点的顺式异构体比反式异构体更为有利,并且 1 在 C-3' 位点的酰基部分需要适当的分子大小。
