关於山道年及其一类物的相对構型問題,可以說现在已經完全解决。这种研究工作,差不多都是作者等歷年來所進行的,所有我們的推論,現在在國际上似乎都被認为正确。本文綜合討論所有这种工作及日本学者关於絕对構型和若干合成工作以及所有欧美近來發表的有关相对及絕对構型的論文。若干变質山道年及其衍生物,因隣近地位影响,致有光学上特殊的变动,於是在構型問題上似有更進一步加以解釋的必要。最近作者更用消除一部分旋光中樞的实驗來解答这种問題。
It can be said that the issue of the relative configuration of the Hill Road Year and its related categories has now been completely solved. Almost all such research work has been carried out by the author over the years, and all our inferences now seem to be considered correct internationally. This article examines all such work in combination with the recent literature by Japanese scholars on both absolute and synthetical work and all recent European and American relative and absolute configurations. A number of metamorphic Hill Roads and their derivatives, due to the influence of neighboring status, have caused a special optical change. Therefore, it seems necessary to explain the configuration issue further. More recently, the authors answered this question with experiments that eliminate part of the optical center.
