An efficient procedure for the synthesis of 2‐aminoisoindolin‐1‐ones via a palladium‐catalyzed three‐component reaction of 2‐halobenzaldehydes, hydrazines and carbon monoxide is reported. This cyclocarbonylation process can be performed smoothly under 1 atmospheric pressure of carbon monoxide to afford 2‐aminoisoindolin‐1‐ones in moderate to excellent yields.
据报道,通过钯催化的2-卤代苯甲醛,肼和一氧化碳的三组分反应,可以合成2-氨基异吲哚-1-酮的有效方法。此环羰基化过程可在1个大气压的一氧化碳下平稳进行,从而以中等至极好的收率得到2-氨基异吲哚啉-1-酮。
