It turned out to be that Ling comprehended many low class tricks in Wu-lin, including the dazing incenses and knockout drops. Tung's anesthetic is actually one kind of them, too. Therefore, when tasted something weird in the soup then, she told, on the quite, a servant to prepare the freshening mint ointment after meal and wake her with it if she falls asleep later. Once the drug effect was relieved, Ling bought a best horse and hurried to the everwinter valley. So, she arrives here not much later than Shin does.
原来金灵以前在跟父亲斗智，企图闯出无银堡时，曾学过有关迷香和蒙汗药等江湖伎俩，童氏安神茶当然也属此类，当时她发现汤的味道有异，就在饭后悄悄嘱咐了一个家仆，要他准备好提神醒脑的薄荷油膏，要是之后发现自己昏睡，就以此将自己弄醒，等解了药性之后，她便买了一匹最好的骏马，向长冬谷直赶而来，所以只比童心，晚了半个时辰左右

The results showed that the addition leading to -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 7 could proceed with good diastereoselectivity and excellent yield (95%).(3) The selective N-deprotection of -2-phenyl-2-(2-vinylpiperidin-1-yl) ethanol 2 without affecting the vinyl group in the substrate were untaken.(4) The Zip reaction for the transformation of -1-(3-aminopropyl)-3-methylazecan-2-one 8 to -7-Methyl-1, Sdiaza-cyclotetradecan-6-one 9 were undertaken. The results showed that, under controlled conditions, acceptable yields (43%) could be achieved and racemization can be minimized during the ring expansion reaction.
该合成路线与文献方法相比，反应条件较温和，也缩短了反应时间；(2)哌啶衍生物2与乙烯基格氏试剂进行加成反应的条件和立体选择性，取得了较好的结果（差向异构体比为80：20，产率95％左右）；(3)不饱和哌啶衍生物7在不影响碳碳双键的情况下去除苯基甘氨醇手性辅助基的条件；(4)具有羰基α位手性的氨基酰胺8在不同条件下经Zip重排反应转变为9的反应，控制反应条件，可使反应中消旋化减小到最小的程度。
