ChemInform Abstract: Enantiomerically Pure 7‐Oxabicyclo(2.2.1)hept‐5‐en‐2‐yl Derivatives (“Naked Sugars”) as Synthetic Intermediates. Part 11. Total Syntheses of (‐)‐Conduritol B (V) ((‐)‐1L‐Cyclohex‐5‐ene‐1,3/2,4‐tetrol) and of (+)‐Conduritol F (IV) ((+)‐1D‐Cyclohex‐5‐ene‐1,2,4/3‐tetrol). Determination of the Absolute Configuration of (+)‐Leucanthemitol.

Abstract

AbstractTo solve literature ambiguities, the title compounds (V) and (VI) are prepared stereospecifically starting from the "naked sugar" (+)‐(I), and (+)‐conduritol F (V) is found to be identical with natural (+)‐leucanthemitol.
