The addition of diphenylcyclopropenone 2 to several enamines 1 as described by Ciabattoni & Berchtold [1] [2] has been reinvestigated. The products which were previously postulated to be enamines of β-dicarbonylcompounds 9 to 14 have now been shown to be ‘amides’ 16 to 20. The reaction does not take the course of a ‘C, C-insertion’, which would have been useful for ring expansion, but rather of a ‘C
如Ciabattoni&Berchtold [1] [2]所述,已将二苯基环丙烯酮2加至几种烯胺1中。先前假定为β-二羰基化合物9至14的烯胺的产物现已显示为“酰胺” 16至20。该反应不采用“ C,C插入”的过程,该过程对于环的扩展是有用的,而是采用“ C,N插入”的过程,该过程连接一个C 3。烯胺的α-碳的侧链。通过对光谱数据的新解释以及对新旧产品的化学转化得出了这一结论。在该再调查,一类新的产品的过程中,氨基-环戊烯酮41,45和47,从该烯胺cyclopro-penone反应中分离。通过光谱考量和化学降解证明了它们的结构。
