nitrocompounds, in the presence of dipolarophiles and a tertiary diamine (e.g., DABCO), undergo dehydration to afford directly isoxazoline derivatives, formal cycloadducts of nitrile oxides; this mild procedure is very efficient for the synthesis of the reported isoxazolines.
在偶极亲和剂和叔二胺(例如,DABCO)存在下,活化的硝基化合物进行脱水作用,直接得到异恶唑啉衍生物,即腈氧化物的正式环加合物。这种温和的程序对于合成已报道的异恶唑啉非常有效。
