Abstract
Summary The action of bases on o-acylaminobenzyltri- phenylphosphonium salts gives indoles in high yields. ... MADELUNG synthesis of indoles1 by cyclization of o-methyl- anilides is initiated only by strong bases at elevated temper- atures and the useful scope of this synthesis is therefore limited to molecules which can survive these very drastic conditions. We report herein a new general synthetic procedure for the synthesis of indoles which is based on the ...
