The present invention provides 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-viral 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).
本发明提供了一种方法,以高产率轻松获得α-氨氧酮化合物,该化合物是单糖和戊糖的合成等效物,以及α-羟基酮化合物的等效物,可用作各种生理活性物质的合成中间体,为从α-氨氧酮化合物诱导的α-羟基酮化合物合成单糖并进一步合成寡糖铺平道路,并为合成各种糖类药物如抗癌剂、抗凝血剂、抗病毒剂、抗HIV剂、胆固醇合成抑制剂、痢疾毒素中和剂开辟新的可能性。根据本发明,允许羰基化合物与亚硝基化合物反应,使用包含在一般式(I)中的杂环化合物的催化剂(其中X1、X2和X3独立地表示氮、碳、氧或硫;Z表示取代或未取代的5至10元环)。
