cycloadds to Nenitzescu's hydrocarbon 1 [6] with skeletal rearrangement. The major adduct 6 can conveniently be transformed to the azo compound 8, which upon photolysis or thermolysis yields up to 80 % pentacyclo[3.3.2.02,4,.03,7.o6,8]dec-9-ene (“ snoutene ”).
4-苯基-1,2,4-三唑啉-3,5-二酮容易被骨架重排环化成Nenitzescu的烃1 [6]。主加合物6可以方便地转化为偶氮化合物8,在光解或热解后,该化合物最多可生成80%的五环[3.3.2.0 2,4, .0 3,7 .o 6,8 ] dec-9-ene( “ snoutene”)。
