  Modular Total Synthesis of Lamellarin D

  摘要：

  A modular total synthesis of lamellarin D, a marine alkaloid with potent cytotoxic as well as topoisomerase I inhibition properties, has been accomplished. A sequential and regioselective bromination/Suzuki cross-coupling procedure was applied for the introduction of aryl groups at positions 1 and 2 of scaffold 1. Microwave-assisted 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) oxidation to yield pyrroloisoquinoline 15, followed by phenol group deprotection and subsequent lactonization, gave lamellarin D (18% in eight steps from 1).

• Design and Synthesis of Lamellarin D Analogues Targeting Topoisomerase I

  synthetic route to rationally designed lamellarin D analogues, 1-dearyllamellarin D (1) and 1-substituted 1-dearyllamellarin D (2), has been developed. The key pentacyclic intermediate 22 was prepared by palladium-catalyzed direct arylation of 12, which in turn was synthesized via C-2-selective lithiation of 15 followed by palladium-catalyzed cross-coupling as the key reactions. Compound 22 was converted

  已经开发了一种一般的合成路线，以合理设计lamellarin D类似物，1-dearyllamellarin D（1）和1-取代的1-dearyllamellarin D（2）。关键的五环中间体22是通过钯催化的12的直接芳基化制备的，该芳基化反应又是通过15的C-2-选择性锂化反应，然后通过钯催化的交叉偶联作为关键反应而合成的。通过区域选择性亲电取代和钯催化的交叉偶联反应，将化合物22转化为多种C-1-取代的类似物2。

  DOI：10.1016/j.tetlet.2005.01.145

  日期：2005.3

  Efficient modular synthetic routes to open chain marine alkaloids such as lamellarins have been developed. 5,6-Dihydropyrrolo[2, 1-b]isoquinoline scaffolds were prepared, and protocols enabling regioselective bromination followed by Suzuki cross-coupling were established for the introduction of aryl groups onto the 2- and 3-positions.
