Lithiation of various Nâ²-benzyl-N,N-dimethylureas with t-BuLi (3.3 mole equivalents) in anhydrous THF at 0 °C followed by reactions with various electrophiles afforded the corresponding 3-substituted isoindolin-1-ones in high yields.
在 0 °C 的无水四氢呋喃中,用 t-BuLi(3.3 摩尔当量)锂化各种 Nâ²-苄基-N,N-二甲基脲,然后与各种亲电物反应,以高产率获得了相应的 3-取代异吲哚啉-1-酮。
