formation (C–C, C–N, C–O). The design, synthesis, and comprehensive utilization of diazanorbornene systems incorporating a flexible hydroxy group are described. The Lewis acid catalyzed intramolecular rearrangement of these strained alkenes gave cyclopentannulated dihydro-2H-pyrans, whereas the intermolecular sequential Lewis acid/palladium-mediated reaction with o-iodoanilines gave pentacyclic frameworks
摘要 描述了结合了柔性羟基的二氮杂降冰片烯系统的设计,合成和综合利用。Lewis酸催化这些应变烯烃的分子内重排产生了环戊二烯化的二氢-2 H-吡喃,而分子间顺序的Lewis酸/钯与邻碘代苯胺的介导反应则通过形成多个键而形成了五环骨架(C–C,C–N, C–O)。 描述了结合了柔性羟基的二氮杂降冰片烯系统的设计,合成和综合利用。Lewis酸催化这些应变烯烃的分子内重排产生了环戊二烯化的二氢-2 H-吡喃,而分子间顺序的Lewis酸/钯与邻碘代苯胺的介导反应则通过形成多个键而形成了五环骨架(C–C,C–N, C–O)。
