  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).

  The marine alkaloid, Lamellarin D (Lam-D), has shown potent cytotoxicity in numerous cancer cell lines and was recently identified as a potent topoisomerase I inhibitor. A library of open lactone analogues of Lam-D was prepared from a methyl 5,6-dihydropyrrolo[2,1-a] isoquinoline-3- carboxylate scaffold (1) by introducing various aryl groups through sequential and regioselective bromination, followed by Pd(0)-catalyzed Suzuki cross-coupling chemistry. The compounds were obtained in a 24-44% overall yield, and tested in a panel of three human tumor cell lines, MDA-MB-231 (breast), A-549 (lung), and HT-29 (colon), to evaluate their cytotoxic potential. From these data, the SAR study concluded that more than 75% of the open-chain Lam-D analogues tested showed cytotoxicity in a low micromolar GI(50) range.
