The present invention is to provide a method for easily obtaining α-aminooxyketone compound which is a synthetic equivalent for monosaccharide and pentoses, and a equivalent of α-hydroxyketone compound that can be synthetic intermediates of various physiologically active materials, in high yield; to pave the way for the synthesis of monosaccharide and furthermore of oligosaccharide from the resulting α-hydroxyketone compound induced from α-aminooxyketone compound; and to open new possibilities for the synthesis of various sugar medicines such as anticancer agents, antithrombogenic agents, anti-HIV agents, inhibitors of cholesterol synthesis, verotoxin neutralizing agents. According to the invention, a carbonyl compound is allowed to react with a nitroso compound to produce an α-aminooxyketone compound using a catalyst containing a heterocyclic compound shown in the general formula (I) (wherein X1, X2 and X3 independently represent nitrogen, carbon, oxygen or sulfur; and Z represents a substituted or unsubstituted 5-to 10-membered ring).
本发明的目的是提供一种方法,便于高产率地获得α-氨基氧酮化合物,它是单糖和戊糖的合成等价物,也是可作为各种生理活性物质合成中间体的α-羟基酮化合物的等价物;为从α-氨基酮化合物诱导出的α-羟基酮化合物合成单糖和寡糖铺平道路;为合成各种糖类药物,如抗癌剂、抗血栓形成剂、抗艾滋病毒剂、胆固醇合成抑制剂、verotoxin 中和剂等提供新的可能性。根据本发明,使用含有通式(I)所示杂环化合物(其中 X1、X2 和 X3 独立代表氮、碳、氧或硫;Z 代表取代或未取代的 5 至 10 元环)的催化剂,使羰基化合物与亚硝基化合物反应生成 α-氨基氧酮化合物。
