The synthesis of a protected 9,9′,10,10′-tetradehydro-disorazole C1 is described. A C1–C8 oxazole fragment with an E-vinylic iodide terminus is coupled to a suitable C9–C19 enyne. The resulting ω-hydroxycarboxylic acid is cyclodimerized stepwise via intermolecular esterification, followed by lactonization. In addition, simplified masked analogues of disorazole C1 with truncated side chains are prepared
描述了受保护的 9,9',10,10'-四脱氢-二恶唑 C1 的合成。带有 E-乙烯基碘化物末端的 C1-C8 恶唑片段与合适的 C9-C19 烯炔偶联。所得ω-羟基羧酸通过分子间酯化逐步环二聚,然后内酯化。此外,还制备了具有截短侧链的 disorazole C1 的简化掩蔽类似物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
