A short and efficient synthesis of 1-(2-oxido-1,2,5-oxadiazol-3-yl)alkyl nitrates from 3-alkyl-1,2,5-oxadiazole 2-oxides, using a mixture of nitric and sulfuric acids in chloroform, has been developed. The scope of the unconventional reaction was established; its mechanism likely included a new Grob-type fragmentation.
使用硝酸和硫酸的混合物从3-烷基1,2,5-恶二唑2-氧化物短而有效地合成1-(2-氧化-1,2,5-恶二唑-3-基)烷基硝酸盐已开发出氯仿中的酸。确定了非常规反应的范围;其机制可能包括新的Grob型碎片。
