Dimercuration of tetrapropoxy calix[4]arene followed by a reaction with isoamyl nitrite afforded dinitroso regioisomers with unique substitution patterns. The unusual conformational behaviour of these inherently chiral systems was revealed by the combination of dynamic NMR and residual dipolar coupling (RDC) techniques.
四丙氧基杯[4]芳烃经双汞化反应后，再与异戊基亚硝酸酯反应，得到具有独特取代模式的二亚硝基区域异构体。通过动态核磁共振和残余偶极耦合（RDC）技术相结合，揭示了这些固有手性体系不同寻常的构象行为。
