The cycloaddition 1,3-dipolar of nitrile oxides to sugar nitro olefins and α,β-unsaturated carbonyl olefins has been investigated. The reaction is less regioselective that the cycloaddition of diazoalkanes to the same olefins and while nitrile oxides with bulky substituents afford the sterically less hindered cycloadducts, other nitrile oxides yield a mixture of the two possible regioisomers. However
已经研究了腈氧化物与糖硝基烯烃和α,β-不饱和羰基烯烃的环加成1,3-偶极。该反应的区域选择性较小,以至于重氮
烷烃与相同的烯烃进行环加成反应,并且具有较大取代基的腈氧化物在空间上受阻的环加合物数量较少,而其他腈氧化物则产生两种可能的区域异构体的混合物。然而,该反应似乎是高度立体选择性的,并且在所有研究的情况下均获得了单个非对映异构体。
