Indium(III) bromide has been used for the first time for the synthesis of imidazo[1,2-a]pyridines in a one-pot operation from 2-aminopyridine, aldehydes, and alkynes. InBr3 was found to be more effective for the activation of both alkyne and imine derived from aryl aldehyde and 2-aminopyridine.
溴化铟(III)首次用于由一锅操作由2-氨基吡啶,醛和炔烃合成咪唑并[1,2- a ]吡啶。发现InBr 3对于活化衍生自芳基醛和2-氨基吡啶的炔烃和亚胺都更有效。
