Antiprotozoal agents as water soluble singlet oxygen photosensitizers: Imidazo[1,2-a]pyridine and 5,6,7,8-tetrahydro-imidazo[1,2-a]pyridine derivatives

Journal of Luminescence, 2017
Abstract In this study we report on the photophysical properties of some imidazo[1,2-a]pyridine and 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine derivatives and their efficiency as singlet oxygen photosensitizers in aqueous media. In aqueous solution, the wavelengths of maximum absorption are in the range of 269–307 nm, while the wavelengths of maximum ...

Metal-Free Synthesis of Trifluoromethyl Carbinol-Containing Imidazo[1,2-a]pyridines via Dehydrative Coupling of Imidazo[1,2-a]pyridines with Trifluoroacetaldehyde

Synthesis
AbstractA facile and efficient method for the synthesis of trifluoromethylated carbinols has been developed from imidazo[1,2-a]pyridines and trifluoroacetaldehyde. The direct C(sp2)–H hydroxytrifluoromethylation is successfully implemented at room temperature using HFIP as solvent through dehydrative cross-coupling process, which displays a broad ...
