A facile and efficient one-pot procedure for the preparation of functionalized dihydro-1H-indol-4(5H)-ones by a catalyst-free, three-component reaction of 1,3-dicarbonyl compounds, arylglyoxal monohydrate and enaminones under mild conditions in excellent yield is reported. This synthesis was confirmed to follow the group-assisted-purification (GAP) chemistry process, which can avoid traditional purifications
一种简便有效的一锅法,用于在温和条件下通过无催化剂的1,3-二羰基化合物,芳基乙二醛一水合物和烯胺酮的三组分反应制备官能化的二氢-1H-吲哚-4(5H)-酮据报道,其收率极高。证实该合成遵循组辅助纯化(GAP)化学过程,该过程可避免传统的纯化,色谱法和重结晶。
