4-methylpentyl-substituted aromatics has been developed using a carbocation relay strategy through selective sp 3 C-H bond activation, providing a facile and cost-effective approach for the construction of benzocyclic compounds. A variety of 1,1-dimethylindane and naphthalene derivatives have been prepared from very simple starting materials in good yields with high selectivity. The present strategy
使用碳阳离子中继策略通过选择性 sp 3 CH 键活化开发了一种高效且选择性的 3-甲基丁基或 4-甲基戊基取代芳烃的分子内 Friedel-Crafts 反应,为构建苯并环提供了一种简便且经济的方法化合物。多种 1,1-二甲基茚满和萘衍生物已由非常简单的原料以高产率和高选择性制备。本策略提供了一个以烷烃为烷基化组分的 Friedel-Crafts 反应的新例子,并构成了选择性 CH 键活化和烷烃衍生物功能化的便捷方法。
