An efficient method for the synthesis of 2,4,6-triaryl-pyridinesvia microwave-promoted and BF 3 ˙OEt 2 -catalysedone-pot reaction of ω-pyrrolidinoacetophenone with chalconeis reported. This method illustrates urea as an environmentallybenign source of ammonia for the synthesis of 2,4,6-triarylpyridines.
报道了一种通过微波促进和BF 3 ˙OEt 2 -催化的ω-吡咯烷苯乙酮与查耳酮的酮锅反应合成2,4,6-三芳基-吡啶的有效方法。该方法说明尿素是合成 2,4,6-三芳基吡啶的环境友好型氨源。
