1H NMR spectroscopy from the measurement of the integrals attributed to the β-methyl groups for each of the diastereoisomers. The configuration of 10 was confirmed by its synthesis using an alternative route. This involved reacting the lithium anion of isoxazolidinone 9 with the acyl chloride derivative of (R)-citronellic acid. GC-MS analysis of this derivative showed a retention time 16.26 min and the corresponding diastereoisomer derived from(S)-citronellic acid had a retention time of 16.12 min. GC-MS analysis of compound 10, mixture of diastereisomers, showed a major peak with a retention time of 16.11 min and a minor peak with retention time of 16.25 min. With these data we were able to confirm the configuration of the major diastereoisomer of 10 as C3-(S).
