Notes:
The concerted applications of a variety of one- and two-dimensional NMR techniques (COSY, NOESY, HETCOR, COLOC, etc.) to the structural elucidation of the natural 3,4-bis[(3,4-dimethoxyphenyl)methyl]dihydro-(3R-trans)-2(3H)-furanone, isolated from Oenanthe aquatica fruits, in CDCl3 solution are reported. The magnitude of the 1H,1H coupling constants obtained from the simulated spectrum together with a series of homonuclear NOE difference spectra were used to determine the full stereochemistry of the system.
