NOVEL HYDROFURAN DERIVATIVES, ITS PREPARATION AND ITS APPLICATION TO NOVEL HYDROISOBENZOFURAN DERIVATIVES AND ITS PREPARATION METHOD

摘要

PURPOSE: A method for preparing a novel hydrofuran derivative is provided to simply obtain a hydrofuran derivative using a cheap copper catalyst. CONSTITUTION: A novel hydrofuran derivative contains a hydroisobenzo-furan derivative of chemical formula 1. In chemical formula 1, R^1 or R^2 is independently hydrogen, (C1-C6)alkyl group, (C1-C6)alkoxy, (C1-C6)alkoxycarbonyl, (C3-C20)cycloalkyl, (C6-C20)aryl, or (C3-C20)heteroaryl.
