Thermolyses of β-aminoacetylenes with a terminal acetylenic bond and of β-amino-olefins afford retro-ene reactions in which nitrogen acts as the hydrogen donor, whereas alkyl subsitution on the terminus of the acetylenic bond leads to a novel, facile cyclization to a 2-alkylidenepyrrolidine.
具有末端炔键的β-氨基乙炔和β-氨基烯烃的热解反应可发生逆烯反应,其中氮充当氢供体,而炔键末端上的烷基取代导致新的,容易的环化成α 2-亚烷基亚吡咯烷。
