The enamines from cyclopropyl-methyl-, -ethyl- and -cyclopentylketone have been prepared by reaction of the ketone with a secondary amine and TiCl4. Their vinylcyclopropane structure has been demonstrated by NMR. The reaction of dicyclopropylketone, cyclopropylphenylketone or cyclopropyl-α-thienylketone with secondary amines and TiCl4 afforded homoallylic rearrangement products, namely 1-cyclopropyl-
环丙基-甲基-,-乙基-和-环戊基酮的烯胺是通过酮与仲胺和TiCl 4反应制备的。它们的乙烯基环丙烷结构已通过NMR证实。二环丙基酮,环丙基苯基酮或环丙基-α-噻吩基酮与仲胺和TiCl 4的反应提供了均烯丙基重排产物,即1-环丙基-,1-苯基-和1-(α-噻吩基)-1,4-二氨基-1-丁烯。
