2 column separation was determined by converting separately into the following cyclic compounds and comparing their coupling constants. The small coupling constants of 4-5 Hz as in 8syn are generally assigned to the trans oxazolidinones [(a) Ref. 1a and references cited therein. (b) Yokomatsu, T.; Yuasa, Y.; Shibuya, S. Heterocycles, 1992, 33, 1051 and references cited therein. (c) Dondoni, A.; Fantin, G.; Fogagnolo, M.; Pedrini, P. J. Org. Chem. 1990, 55, 1439]. The large coupling constants of 8-10 Hz as in 8anti are typically due to the diaxial relationship between the two adjacent protons in six-membered rings [Pretsch, E.; Bühlmann, P.; Affolter, C.; Structure Determination of Organic Compounds, 3rd ed.; Springer: Berlin, 2000; pp 161-198]. The sense of asymmetric induction caused by the N,N-diBoc group was confirmed further by stereoselective syntheses of the known derivatives of both diastereomers, d-ribo- and l-arabino-phytosphingosine, from each dihydroxylation product as described in the text.{A figure is presented}.
