    • Selected NOE enhancements are collected in the Supporting Information. NOE irradiation of H3′ in syn-(+)-4a resulted in enhancement of the signal corresponding to H4 (3%). Conversely, the same NOE enhancement was observed for H3′ upon irradiation of H4, which is consistent with a syn relative stereochemistry between H4 and H3′ and R configuration at C3′. A NOE enhancement of 0.2% for H4 in anti-(+)-4a on irradiating the signal corresponding to H3′ is in good agreement with an anti relative disposition between H3′ and H4 in anti-(+)-4a (S configuration at the new stereogenic center at C3′).
