An aminoalcohol is synthesized by reacting a cyclic hemiacetal expressed by Formula 1
(where n is 0 or 1; R1 and R2 are each a hydrogen atom, a monovalent saturated hydrocarbon group which is optionally substituted, or a monovalent aromatic group which is optionally substituted, or R1 and R2 are bonded together into a divalent saturated hydrocarbon group which is optionally substituted; and R3, R4, and R5 are each a hydrogen atom, a monovalent saturated hydrocarbon group which is optionally substituted, or a monovalent aromatic group which is optionally substituted), with hydrogen and any one of ammonia, a primary amine and secondary amine in the presence of a hydrogenation catalyst.
通过在存在氢化催化剂的情况下,将由式1表示的环状半缩醛(其中n为0或1;R1和R2分别为氢原子、一个饱和的单价碳氢基团,可选择性地取代,或一个饱和的芳香基团,可选择性地取代,或R1和R2结合成一个饱和的双价碳氢基团,可选择性地取代;而R3、R4和R5分别为氢原子、一个饱和的单价碳氢基团,可选择性地取代,或一个饱和的芳香基团,可选择性地取代)与氢和氨、一级胺或二级胺之一反应,合成氨基醇。
