13C NMR spectroscopy of D and B, D-ring seco-limonoids of Meliaceae family.


The modified limonoids isolated from the Meliaceae are too complex or obtained in too small quantities to determine their structures by chemical and spectroscopic means, including 1H NMR. One method of dealing with such problem is direct crystallographic analysis, without or having a heavy atom, which requires an able crystallographic collaborator. The… (More)
