    • The relative stereochemistry at C-7 to C-9 in adduct 22 was determined after 8, 10-syn reduction of the keto group followed by protection of the 8, 10-diol as the corresponding acetonide. H, H-Coupling constants in the six-membered ring and NOE-correlations served as diagnostic tools for this purpose
