(-)-Epibatidine, an excellent candidate of non-opioidal anesthesia, was formally synthesized in short steps from di-(l)-menthyl (R)-allene-1,3-dicarboxylate that was facilely prepared as a single isomer by means of crystallization-induced asymmetric transformation from a diastereomer mixture of (R)- and (S)-allene-1,3-dicarboxylates. Taking advantage of the chiral synthesis, derivatives of (-)-epibatidine
(-)-Epibatidine是一种非阿片类药物的极好的候选药物,它是由二-(l)-薄荷基(R)-丙二烯-1,3-二羧酸酯在短时间内正式合成的,方法很简单,即(R)-和(S)-丙二烯-1,3-二羧酸酯的非对映异构体混合物的结晶诱导的不对称转变的机理。利用手性合成的优势,还制备了(-)-表巴替丁衍生物,以靶向可与哺乳动物中枢神经系统中的烟碱乙酰胆碱受体(nAChRs)结合的诊断剂。
