【文章名】The Ullmann Coupling between 2-Chlorobenzoic Acids and Amino Acids; A Valuable Reaction for Preparing 2-Substituted 1-Acetyl-1H-indol-3-yl Acetates
[摘要]: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 Rossing method in moderate to good yields.
