A synthetic approach to a structurally novel series of indoline 2,2-biscarboxylates is described that employs a tandem bis-alkylation strategy to cyclize the indoline heteroring from the bromide 7 and diethyl bromomalonate. The indolines thus prepared may be N-deprotected and further functionalized on the indoline nitrogen.

Thermolysis of 2-(N-acylamino)benzyl methyl ethers, in the presence of an acid catalyst and triphenylphosphine, or 2-(N-acylamino)benzylphosphonium salts is found to serve as a novel method for indole formation, in particular for the synthesis of 2-trifluoromethylindoles. The reaction of the benzyl methyl ethers is suggested to involve a phosphonium intermediate, which thermally decomposes to the indoles.
