摘要

The Diels-Alder reactivity of two captodative olefins, 2-morpho-lino-acrylonitrile 15 and 2-(N- methlanilino)-acrylonitrile 16, towards four conjugated dienes is evaluated. In every cases, isomeric {4+ 2} cyclo-adducts are obtained. With olefin 15 yields are better than with olefin 16. The adducts are easily transformed in to the corresponding ketones by a mild hydrolysis of the α-aminonitrile group. Thus, the 1-cyanoenamines can be considered as good ...
