The reactions of triphenylpyrylium salt 1 with various anuno acids were explored and compared. The reactions with most α-amino acids yielded decarboxylation products 2 via decarboxylation. The reactions with glutamic acid, lysine and ACC (1-aminocyclopropyl-carboxylic acid) gave triphenylpyndine 8, dimer 9 and acid 5a-acc, respectively. The reactions with βand γ-amino acids yielded triphenylpyridine by intramolecular elinunation. The reactions of triphenylpyrylium salt 1 with various anuno acids were explored and compared.
