high yields by N-Chlorosuccinimide into hydroxamic acid chlorides, and corresponding nitrile oxides generated by addition of triethylamine at 40°–50° underwent 1,3-dipolar polar addition to alkenes, giving 2-isoxazolines. The whole procedure could be performed as a one-pot reaction. Oximes with other functions, sensitive to free chlorine could be converted selectively into hydroxamic acid chlorides by
N-氯代琥珀酰亚胺将醛糖高产率地转化为异羟肟酸酰氯,在40°-50°C下加入三乙胺生成相应的腈氧化物,将1,3-偶极极性加到烯烃上,得到2-异恶唑啉。整个过程可以作为一锅反应进行。通过该程序可以将对游离氯敏感的具有其他功能的肟选择性地转化为异羟肟酸氯化物。异亚丙基甘油醛肟被添加到丙烯醛二乙基缩醛中,从而提供了碳水化合物合成的入口,但是反应的立体特异性低。通过用NCS和碱处理,将2:3、5:6-二-O-异亚丙基-D-甘露糖肟转化为N-氢西米酸内酯。
