METHODS FOR THE STEREOSELECTIVE PREPARATION OF APIOSE DERIVATIVES FROM ALLYLIC ALCOHOL COMPOUNDS AND ALLENE COMPOUNDS USING CATALYTIC ASYMMETRIC SYNTHESIS
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.
