吡啶化合物通常具有很顯著的生物活性,是許多學者爭相研究的對象。本研究分為兩個主軸: (壹) 3-取代吡啶衍生物,(貳) 4-取代吡啶衍生物。個別探討了3-取代及4-取代的吡啶化合物衍生物,我們提出了新穎的合成方法,更直接更快速的合成出需要的吡啶化合物骨架。
Piperidine derivatives usually have a significant biological activity. This study is divided into two themes : ( 1 ) To synthesize different derivatives from 3-substituded piperidines under acidic condition and using ring closing metathesis. ( 2 ) To synthesize different derivatives from 4-substituded piperidines using diisobutylaluminium hydride ( DIBALH ) These noval synthetic methods are more direct and rapid synthetic approaches to the piperidine skeletons.
