indole (27) with various aldehydes or imines in the presence of thioureaorganocatalysts carrying 3,5-bis(trifluoromethyl)phenyl or 3,5-dichlorophenyl moieties. Reactions were performed under conventional and microwave (MW) irradiation without solvent. The most active organocatalyst for aldehydes was thiourea 3 and for imines, the thiourea 6. For compound 11 derived from 2,4,6-trimethoxybenzaldehyde (30)
