Novel regioselective approach to the synthesis of (1H-1,2,3-triazol-1-yl)furoxans based on Lewis acid-catalyzed Wolff cyclocondensation of aminofuroxans with diazo-β-dicarbonyl compounds has been developed. This approach allows to involve aminofuroxans as substrates which are very weak nucleophiles and usually do not participate in reactions with common electrophiles.
基于路易斯酸催化的氨基呋喃与重氮-β-二羰基化合物的沃尔夫环缩合反应,已经开发了合成(1H-1,2,3-三唑-1-基)呋喃的新型区域选择性方法。这种方法允许将氨基呋喃作为底物,它们是非常弱的亲核试剂,通常不参与与普通亲电试剂的反应。
