corresponding 1-hydroxy-1-piperidinocyclopropane, conveniently prepared from the piperidide of 3-chloropropionic acid, react as cyclopropanone equivalents with various nucleophiles. Use of these derivatives in the formation of pyrroles, pyrrolines and pyrrolizidines is described. The rearrangement of dicyclopropyl ketimines is explored.

cyclopropyl pyrrolines resulting from SN2 ring-opening by the nucleophilic halide. In the absence of a nucleophilic counterion, the acid-catalyzed thermolyses lead to pyrroles if there can be stabilization of cationic intermediates by an electron-releasing substituent.
在用卤化铵热解时,二环丙基酮亚胺产生环丙基吡咯啉,这是由于亲核卤化物使S N 2开环而产生的。在不存在亲核抗衡离子的情况下,如果可以通过释放电子的取代基稳定阳离子中间体,则酸催化的热解会生成吡咯。
