Abstract :
(1S,2R,3R,4S,5R)- (3a) and (1S,2S,3S,4S,5R)-1,2,3,4,5-pentahydroxy-1-hydroxymethylcyclohexane (4a), (1R,2R,3R,4S,5R)- (3b) and (1R,2S,3S,4S,5R)-1,2,3,4,5-pentahydroxycyclohexan-1-carboxylic acid (4b) are reported. The syntheses exploit the diastereoselective oxidation of the 5,6-double bond of the quinic acid-derived lactone 2 with osmium tetroxide.
