    • The specific reason for the high β-selectivity in the glycosylation of 43 in the absence of the C2-participatory group in 45 is unclear, although it is likely that this outcome is highly substrate dependent.

    • The strategy of using 2,3-di-O-benzylidine-5-O-benzylapiofuranose instead of 76 as a the glycosyl donor for direct coupling with 52 was less attractive, given that such a donor required its preparation from 76 in a low-yielding sequence. Given that the conversion of 52 + 76 → → 77 is nearly quantitative over three steps, the alternate approach would have been considerably less efficient.

    • 1H NMR, and MS data of synthetic S were identical to those of natural S, obtained by RP-HPLC of Quil A (Accurate Chemical & Scientific Corp.), a Quillaja extract known to contain traces of 5.
