The stereochemical revision of two recently reported rhamnofolane diterpenes, curcusones I and J, was enabled by quantum calculations of NMR shifts and coupling constants at DFT levels. DP4+ results and reexamination of the NMR data suggest that curcusones I and J should be revised as CS32 and CS28, respectively.
通过在 DFT 水平上对 NMR 位移和耦合常数进行量子计算，实现了最近报道的两种瑞香烷二萜 curcusones I 和 J 的立体化学修订。DP4+ 结果和对 NMR 数据的重新检查表明，curcusones I 和 J 应分别修订为 CS32 和 CS28。
