2-Substituted 3-acetoxy-1-acetyl-1H-indoles were prepared by condensing 2-chlorobenzoic acids with amino acids under Ullmann conditions in good yields, and further cyclodecarboxylation using the Rössing method in moderate to good yields.
通过在Ullmann条件下,将
2-氯苯甲酸与
氨基酸缩合,制备了2-取代的3-乙酰氧基-1-乙酰基-1H-
吲哚,产率良好;进一步采用Rössing方法进行环脱羧反应,产率从中等到良好。
