The X-ray crystallographic analysis of a labile dehydrosecodine-type intermediate was achieved by designing a functionally modulated analogue, enabling its inclusion within a self-assembled coordination cage. The unique folded conformation of this intermediate, stabilized inside the hydrophobic cavity, was supported by DFT calculations and supports the postulation of its involvement in divergent metabolic pathways to various monoterpene indole alkaloids.

不稳定的脱氢可可定型中间体的合成调制及其在密闭腔中的封装使其能够进行X射线晶体学观察

通过设计功能调制的类似物，使其包含在自组装配位笼内，实现了不稳定的脱氢可可定型中间体的 X 射线晶体学分析。这种中间体独特的折叠构象稳定在疏水腔内，得到了 DFT 计算的支持，并支持其参与各种单萜吲哚生物碱的不同代谢途径的假设。
