Optically active materials of tricyclic compounds, for example, cyclopenta[b] benzofuran derivatives represented by the following formula:
[wherein R1, R2, Y and Z independently represent hydrogen, halogen, an alkyl group, or an aryl group; W represents oxygen, sulfur, nitrogen or carbon; and n represents 0 to 4] are directly produced by adding an optically active alcohol, amine and/or metal salt thereof. The production method of the present invention requires neither complicated optical resolution operation nor enzyme reaction requiring a large amount of solvent and much reaction time and exhibiting low reproducibility, can be applied to both experimental and industrial production methods, and is thus very advantageous.
三环化合物的光学活性材料,例如由下式表示的环戊并[b]
苯并呋喃衍
生物:
[其中 R1、R2、Y 和 Z 独立地代表氢、卤素、烷基或芳基;W 代表氧、
硫、氮或碳;n 代表 0 至 4],通过加入具有光学活性的醇、胺和/或其
金属盐直接生产。本发明的生产方法既不需要复杂的光学解析操作,也不需要大量溶剂和大量反应时间的酶反应,而且重现性低,既可应用于实验生产方法,也可应用于工业生产方法,因此非常具有优势。
