described by using substituted methyl 2-(halomethyl)benzoates and substituted amines. Structurally various methyl 2-(halomethyl)benzoates and amines were transformed into isoindolinones 80–99% yield and purity in catalyst-free and solvent-free conditions. The method has a wide substrate scope. The synthetic utility of the one-pot reaction was demonstrated by the concise syntheses of Lenalidomide intermediate
在本文中,通过使用取代的 2-(卤甲基)苯甲酸甲酯和取代的胺,描述了一种用于简明合成异吲哚啉酮的实用且有效的系统。在无催化剂和无溶剂条件下,结构上各种 2-(卤甲基)苯甲酸甲酯和胺被转化为异吲哚啉酮,产率和纯度为 80-99%。该方法具有广泛的底物范围。来那度胺中间体和 DWP205190 的简明合成证明了一锅反应的合成效用。
