29. 1H NMR spectra, the diastereoisomer ratio can be determined by the integration of the appropiate signal (H at C-2).
30. 12. (a) E.e.s were determined by HPLC on a Chiracel OD column; mobile phase hexane/isopropanol (97/3); flow rate 1 mL/min; detector: UV 254 nm.
31. (b) configurations were assigned by comparison with the sign of the optical rotation and known elution order from a chiracel OD column.
32. 3-THF were used.
