Castagnoli–Cushman reaction was carried out with various fused and bridged bicyclic anhydrides. The influence of the anhydride nature and, specifically, the size of fused anhydride rings on the reaction pathway were investigated. The negative outcome of the reaction in the case of small rings and bridged systems was mechanistically described. The scope and limitations of the procedure involving anhydrides and imines
Castagnoli-Cushman 反应是用各种稠合和桥联的双环酸酐进行的。研究了酸酐性质,特别是稠合酸酐环的尺寸对反应途径的影响。机械地描述了小环和桥接系统中反应的负面结果。讨论了涉及酸酐和亚胺的程序的范围和局限性。证明了该方法具有较高的非对映选择性,并与前期结果具有相关性。该反应经过优化并扩大规模,可在单次运行中提供数克量的产物(最多 50 克)。
