Two successful synthetic routes to trichostatin A (1) are described; one (Scheme 2) uses the γ-alkylation of a silyl dienol ether, the other (Scheme 4) uses a silyl-protected cyanohydrin anion. The two routes bear an upolung relation to each other. The Lewis acid-catalysed acylation of silyl enol ethers is a simple and effective way to prepare β-diketones and β-keto esters (Scheme 1); this reaction
描述了两种成功的曲古抑菌素A(1)的合成途径;一种(方案2)使用甲硅烷基二烯醇醚的γ-烷基化,另一种(方案4)使用甲硅烷基保护的氰醇阴离子。两条路线彼此之间存在着隆隆的关系。路易斯酸催化的甲硅烷基烯醇醚的酰化是制备β-二酮和β-酮酸酯的一种简单有效的方法(方案1);然而,该反应仅使甲硅烷基三烯醚(11)的β-酰化(方案3),并且甲硅烷基三烯醚(11)必须通过环回路线来制备(方案3)。
