  nitrile oxides (MeOCOC≡N→O, PhC≡N→O, and EtC≡N→O) were effectively generated in situ by dehydration of the corresponding primary nitro compounds (RCH2NO2) with PhSO2Cl or ClCOOEt in the presence of triethylamine. Various cycloadducts were prepared by the reaction of them with dipolarophiles. Some advantages of these methods are described in comparison with other known methods.

  在三乙胺的存在下，通过用 PhSO2Cl 或 ClCOOEt 使相应的初级硝基化合物 (RCH2NO2) 脱水，原位有效地生成了三种腈氧化物（MeOCOC≡N→O、PhC≡N→O 和 EtC≡N→O）。各种环加合物是通过它们与偶极试剂反应制备的。与其他已知方法相比，描述了这些方法的一些优点。

  Isoxazolines without the [3+2]: An electrochemical method for the synthesis of isoxazoline cores is presented. Both aryl and more challenging alkyl aldoximes are converted to the desired isoxazoline through an electrochemically enabled regio- and diastereoselective reaction with electron-deficient alkenes. Supporting analyses from kinetic (time-course) modelling and density functional theory support
