摘要

核磁共振(NMR)波谱学的进展是多环“笼”支架结构解析的基石。由于这些化合物的致密性，很多重叠，以及独特的通过空间和键核磁共振相互作用经常被观察到。本文综述了金刚烷、五环癸烷和三环环烷等多环结构衍生物的特征趋势、取代基模式和化学位移行为的一些典型和相关方面，为今后衍生物的核磁共振鉴定提供了指导。关键词:金刚烷，核磁共振解析，五环癸烷，多环化合物，三环癸烷

Trends in NMR Structural Elucidation Of Polycyclic Cages, Namely: Adamantane, Pentacycloundecane and Trishomocubane

ABSTRACT Advances in Nuclear Magnetic Resonance (NMR) spectroscopy is a cornerstone in structure elucidation of polycyclic 'cage' scaffolds. Due to the compactness of these compounds, much overlap, as well as unique through-space and bond NMR interactions are frequently observed. This review serves as a guide for the NMR elucidation of future derivatives by providing some of the typical and relevant aspects of the characteristic trends, substituent patterns and chemical shift behaviour for the identification of the polycyclic structures, namely adamantane, pentacycloundecane and trishomocubane derivatives. Keywords: adamantane, NMR elucidation, pentacycloundecane, polycyclic compounds, trishomocubane
