optically active ketomorphinan 5 afforded the optically active morphinan 6 differing chromatographically and spectroscopically from the material obtained in a Grewe-cyclization of the isoquinoline 1. A single crystal X-ray analysis of a hydrobromide salt of a phenolic amine obtained from 1 and 2 with refluxing hydrobromic acid showed this compound to be the N-methylapomorphinan 4.
沃尔夫- Kishner还原光学活性的酮吗啡喃的5得到的光学活性的吗啡喃6从在获得的材料和色谱光谱不同Grewe异喹啉的-cyclization 1。用回流的氢溴酸对由1和2获得的酚胺的氢溴酸盐的单晶X射线分析表明该化合物为N-甲基阿朴吗啡喃4。
