(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.
(1 S,2 R,3 R,4 S,5 R)-(3a)和(1 S,2 S,3 S,4 S,5 R)-1,2,3,4,5-五羟基- 1-羟甲基环己烷(4a),(1 R,2 R,3 R,4 S,5 R)-(3b)和(1 R,2 S,3 S,4 S,5 R)-1,2,3 ,4,5-五羟基环己-1-羧酸(4b)的报告。该合成利用了奎宁酸衍生的内酯2的5,6-双键与四氧化的非对映选择性氧化。
