versatile synthetic approach to the synthesis of naphthalenic analogs of melatonin, compound 7, and its 2-alkyl substituted analog 8 is described. This approach features the novel synthesis of substituted 1-naphthyl acetonitrile 12 and 19 by nucleophilic addition of LiCH2CN to substituted 1-tetralone, followed by aromatization via a 2-step reaction sequence, dehydrogenation with DDQ and TsOH catalyzed dehydration
描述了一种高效且通用的合成方法,用于合成褪黑激素、化合物 7 及其 2-烷基取代类似物 8 的萘类似物。该方法的特点是通过将 LiCH2CN 亲核加成到取代的 1-四氢萘酮,然后通过 2 步反应序列进行芳构化、用 DDQ 脱氢和 TsOH 催化脱水来合成取代的 1-萘基乙腈 12 和 19。
