Sapidolide A: An unprecedented spherical carbocyclic lactone from Baccaurea sapida seed kernels: Is it a meroisoprenoid ?
摘要:
A novel tetrahydrofurano-lactone meroisoprenoid (sapidolide A) 1 has been isolated from a tropical plant Baccaurea sapida, and its structure has been determined on the basis of DEFT, H-1-H-1 COSY, H-1-C-13 COSY, (+)-FABMS, low energy EIMS, and ion desorption chemical ionization mass spectrometry, and was confirmed by X-ray crystallography of its single crystal.
