    • In the BDA-protection of diol 1, although, the anomeric effect at the two acetal centers favored the formation of the isomer with anti-periplanar arrangement of OMe groups, the other isomer was also formed in minor proportion. This was not separated and the mixture was used as such for ensuing glycosylations. After the removal of BDA protecting group, individual products were obtained in pure form.

    • 1H COSY spectral analysis then established the correlation between all of the protons on each ring. The regioselectivity of glycosylation (O5 or O6) was determined by observation of the correlation with the OH protons in the COSY spectrum, wherever possible, and also judged from the multiplicity of H5 and H6 protons. NOESY spectral analysis was finally used to reaffirm the assignments. The α and β configurations were determined on the basis of coupling constant measurements of the respective anomeric protons (see the Supporting Information).
