  • Total Synthesis of Natural and Unnatural Lamellarins with Saturated and Unsaturated D-Rings
    作者:Poonsakdi Ploypradith、Thaninee Petchmanee、Poolsak Sahakitpichan、Nichole D. Litvinas、Somsak Ruchirawat
    DOI:10.1021/jo061810h
    日期:2006.12.1
    Twenty-eight natural and unnatural lamellarins with either a saturated or an unsaturated D-ring were synthesized according to our developed synthetic route. The key step involved the Michael addition/ring closure (Mi-RC) of the benzyldihydroisoquinoline and alpha-nitrocinnamate derivatives, which provided the 2-carboethoxypyrrole intermediates in moderate to good yields (up to 78% yield). Subsequent hydrogenolysis/lactonization furnished lamellarins with a saturated D-ring in excellent yields (up to 93% yield). DDQ oxidation of the saturated lamellarin acetates led directly to the corresponding unsaturated analogues in 54-95% yield. In addition, only two steps in our developed strategy require column chromatography.
  • Practical Decagram-Scale Synthesis of a Lamellarin Analogue and Deprotection of Lamellarin Isopropyl Ethers
    作者:Robin Klintworth、Charles B. de Koning、Joseph P. Michael
    DOI:10.1002/ejoc.202000499
    日期:2020.7.7
    Lamellarin ε and dehydrolamellarin J were synthesized via enaminones by operationally simple routes that included a mild new method for the nearly quantitative deprotection of isopropyl‐protected phenols with methanesulfonic acid. The synthesis of dehydrolamellarin J could be scaled up to provide over 25 g of product without the need for chromatography.
    Lamellarinε和Dehydrolamellarin J是通过操作简单的途径通过烯胺酮合成的,其中包括使用温和的新方法对异丙基保护的苯酚进行甲磺酸近乎定量的脱保护。可以扩大脱氢薄片蛋白J的合成规模,从而无需色谱即可提供超过25 g的产物。
