(±)-1α-Nitro-2β-[3-(6-chloropyridyl)]-cyclohexanone, a key intermediate for a stereocontrolled synthesis of the alkaloid epibatidine, possessing a 7-azanorbornane structure to which is attached, in an exo-orientation, a 5-(2-chloropyridyl) substituent, has been prepared either by Diels-Alder reaction or tandem Michael reaction by way of 5-(2-nitrovinyl)-2-chloropyridine as common starting material
(±)-1α硝基2β-[3-(6-氯吡啶基)] -环己酮,为生物碱地棘蛙素的立体控制合成的关键中间体,具有7氮杂降冰片烷结构,其上连接,在一个外-orientation ,是通过Diels-Alder反应或串联Michael反应,通过以5-(2-硝基乙烯基)-2-氯吡啶为常见原料和2-三甲基甲硅烷氧基-1,3制备的5-(2-氯吡啶基)取代基-丁二烯或3-氧代-4-戊烯酸甲酯分别作为对应物。
