A short, scalable and environmentally benign synthesis of 2- and 4-substituted benzylpiperidines, e.g. I, has been developed. The method is based on the temperature-programmed consecutive deoxygenation and heteroaromatic ring saturation of aryl(pyridin-2-yl)- and aryl(pyridin-4-yl)methanols and aryl(pyridin-4-yl)methanones in the presence of Pd/C catalyst. The crucial roles of the temperature, the acidity and the substrate structure in the change of selectivity have been demonstrated by isolation of several substituted aryl(piperidine)methanols. The carbinols and ketones were prepared from com. available pyridinecarbaldehydes or 4-cyanopyridine and substituted bromobenzenes via organometallic intermediates.
