C‐3, or C‐4 positions of the piperidine ring based on the formal sp3–sp3 retrosynthetic disconnection is described. Catalytic hydrogenation of these adducts could be performed selectively for the synthesis of (cyclo)alkylpiperidines or the corresponding saturated amino alcohols on up to a 0.5 kg scale.
描述了一种基于形式上的sp 3 –sp 3逆合成断裂,在
哌啶环的C-2,C-3或C-4位置引入(环)烷基取代基的有效方法。这些加合物的催化加氢可以选择性地进行,以合成(环)烷基
哌啶或相应的饱和
氨基醇,规模最大为0.5kg。
