It is an object of the present Invention to provide a process for producing 1,2,3-tri-O-acetyl-5-deoxy-ribofuranose in an industrially appropriate manner. The present invention provides a process for producing a 1,2,3-tri-O-acetyl-5-deoxy-ribofuranose which comprises hydrogenating a compound represented by the formula (1) or formula (2) in the presence of a metal catalyst:
wherein P1 and P2 independently represent a hydrogen atom or an acyl group OP1 and OP2 may together form an acetal group, and R represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, or an acyl group;
wherein X1 represents Br or I, P3 and P4 independently represent a hydrogen atom or an acryl group, and R represents a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, or an acyl group.
本发明的目的是以工业适当的方式提供一种生产1,2,3-三-O-乙酰-5-去氧-核糖呋喃糖的方法。本发明提供了一种生产1,2,3-三-O-乙酰-5-去氧-核糖呋喃糖的方法,其包括在金属催化剂的存在下氢化由化合物表示的化合物(1)或化合物(2):其中P1和P2独立地表示氢原子或酰基OP1和OP2可以共同形成缩醛基,R表示氢原子、烷基、芳基、芳基烷基或酰基;其中X1表示Br或I,P3和P4独立地表示氢原子或丙烯酰基,R表示氢原子、烷基、芳基、芳基烷基或酰基。
