The present invention relates to a method for the stereoselective preparation of apiose derivatives from allylic alcohol compounds and allene compounds using catalytic asymmetric synthesis. The method for the stereoselective preparation of apiose derivatives of the present invention is based on the catalytic asymmetric synthesis from allylic alcohol compounds and allene compounds in the presence of a metal catalyst, so that apiose derivatives can be produced stereoselectively, with high yield, with high optical purity regardless of the types of substituents of the compounds. The method of the invention can also be used for the preparation of oligosaccharides including monosaccharides, disaccharides, and polysaccharides or various compounds including apiose derivatives because the method can minimize the production of by-products without using an activating group, unlike the conventional method for the preparation of adipose derivatives.
本发明涉及一种从烯丙醇化合物和联苯化合物中使用催化不对称合成的方法,用于立体选择性制备阿匹酮衍生物。本发明的阿匹酮衍生物立体选择性制备方法基于金属催化剂存在下的烯丙醇化合物和联苯化合物的催化不对称合成,因此无论化合物的取代基类型如何,都可以高产率、高光学纯度地立体选择性地产生阿匹酮衍生物。本发明的方法还可用于制备低聚糖,包括单糖、双糖和多糖,或各种化合物,包括阿匹酮衍生物,因为该方法可以最小化副产物的产生,而无需使用活化基,与传统的制备阿匹酮衍生物的方法不同。
