one-pot two-step reductive coupling between acetyl naphthalene derivatives, tosylhydrazide, and arylboronic acids, affording substituted 1(or 2)-(1-phenylethyl)naphthalenes in moderate-to-excellent yields, was reported. Notably, solvent played a crucial role in the coupling of 1-acetyl naphthalene derivatives (toluene) or 2-acetyl naphthalene derivatives (1,4-dioxane) as starting materials. Meanwhile,
在这项研究中,报告了乙酰萘衍生物,甲苯磺酰肼和芳基硼酸之间的一锅两步还原偶联,以中等至优异的产率提供了取代的1(或2)-(1-苯乙基)萘。值得注意的是,溶剂在作为起始原料的1-乙酰基萘衍生物(甲苯)或2-乙酰基萘衍生物(1,4-二恶烷)的偶联中起关键作用。同时,该一锅偶联反应的范围扩展到了1(或2)-萘醛底物。特别地,该系统也适合于以克数级合成1(或2)-(1-苯乙基)萘,并且被用于合成萘甲基甲基取代的咔唑基化合物。
