chloroenamines 2a-d at room temperature. At elevated temperatures the rearranged amidine 10a was the reaction product from 2a and cyanide. Rearranged amidines 10a-c also were accessible by heating 9a-c in the presence of cyanide. Chlorocyclododecene carboxamide 2e gave a cyanobicycloalkane carboxamide 18e in which a trans position of the carboxamide and the cyano moiety prevented a ring closure. Amidine 19 and
三环.9a-d是在室温下由
氰化物与
氨基甲酰化的
氯亚胺2a-d反应制得的。在升高的温度下,重排的am10a是2a与
氰化物的反应产物。通过在
氰化物存在下加热9a-c,也可以得到重排的am10a-c。
氯环十二碳烯羧酰胺2e给出了
氰基双环
烷烃羧酰胺18e,其中羧酰胺和
氰基部分的反式阻止了环的闭合。
氢化铝锂9a生成generated19和三
氨基衍
生物20。类似地,10a得到am 21。
