2 A. General methods 1 H and 13 C MR spectra were recorded on a 400 MHz spectrometer using CDCl 3 as solvent and TMS as an internal standard. Mass spectra were obtained with gas chromatography mass spectrometer. IR spectra were obtained either as potassium bromide pellets or as liquid films between two potassium bromide pellets with a spectrometer. GC MS was obtained using electron ionization. HRMS was obtained with a LCMS-IT-TOF mass spectrometer. B. General procedure for the synthesis of pyrrole derivatives -Allylamine (0.2 mmol), bromoalkynes (0.2 mmol), PdCl 2 (10 mol %) and BQ (2 equiv) were added to 2 ml toluene/dmso (5/1). The mixture was stirred under air at 110 o C for the desired reaction time. After that, water was added and extracted with ethyl acetate twice. The combined organic phase was dried over a 2 SO 4 and concentrated. The residue was eventually purified by flash column chromatography on silica gel with petroleum ether/ethyl acetate as the eluent to afford the corresponding pyrroles. C.
