Popis: | The (4+2) cycloaddition of methyl 1-diethylamino-2-ethyl-1,3-butadiene-1-carboxylate was performed with acrylonitrile. The cycloadduct bridges over to form 1-diethylamino-6-ethyl-bicyclo [2.2.1] hept-5-ene-7-one-2-carbonitrile 3. We demonstrate that this latter product underoges facile [1,3] sigmatropic rearrangement. |
