The library of all possible bis-Mosher esters (16) was then made by esterification. Complete sets of 1H, 13C, and (for the Mosher esters) 19F NMR spectra were recorded, assigned, and compared with each other and with published spectra. Not all of the spectra are unique, and the 1H NMR spectra of the Mosher esters provided the most information. The previous assignment of the natural sample as an "all-R" stereoisomer mixed with its 3S-epimer was confirmed. {\copyright} 2011 American Chemical Society.} }
