Teraryls, quateraryls, and quinquearyls composed of a pyridine ring in the segment and their vinylogues were prepared directly by thermal rearrangement of N-(hetero)arylmethyl-2,2-dichloro-1-substituted phenylcyclopropylmethyleneamines in modest to good yields.
通过对 N-(杂)芳基甲基-2,2-二
氯-1-取代苯基环丙基亚甲基胺进行热重排,直接制备了在段中由一个
吡啶环组成的三元、四元和五元及其
乙烯基对映体,收率从一般到良好。
