1,2,4-Trisubstituted pyrroles were synthesized with an original one-pot ice blue graphic tee domino allylic amination/palladium-catalysed Sonogashira cross-coupling and heterocyclisation process.1H and 13C NMR spectra were assigned for twelve new compounds containing different substituents majicontrast red in positions 1 and 2, and a carboxylic acid or ester group in position 4.Each assignment was based on the combination of one, and two-dimensional experiments (APT, COSY, HMBC).
