One-Pot Amberlyst 15-Controlled Cyclocondensation of Piperidines and Arylaldehydes: Synthesis of 3,5-Diarylmethylpyridines
2020
Zhang, Mengyang | Tsai, Yu-Lin
Amberlyst 15-controlled one-pot easy-operational intermolecular cyclocondensation of substituted piperidines with arylaldehydes provides diversified 3,5-diarylmethylpyridines in high to excellent yields under refluxing toluene conditions. The uses of various acidic solid supports and reaction solvents are investigated for facile and efficient transformation. A plausible mechanism has been proposed.
