By a combination of stereospecific osmium catalyzed oxidation of dimethyl citraconate and lipase catalysed enantioselective resolution of the formed dimethyl (2R*,3S*)-2,3-dihydroxy-2-methylbutanedioate, followed by reduction, (2R,3S)- and (2S,3R)-2-methylbutane-1,2,3,4-tetraol were isolated. Similar reactions starting with dimethyl mesaconate gave the isomers, (2R,3R)- and (2S,3S)-2-methylbutane-1
通过立体定向锇催化氧化柠檬酸二甲酯和脂肪酶催化对映选择性拆分形成的 (2R*,3S*)-2,3-二羟基-2-甲基丁二酸二甲酯,然后还原,(2R,3S)-和 ( 2S,3R)-2-甲基丁烷-1,2,3,4-四醇被分离。以中康酸二甲酯开始的类似反应得到异构体,(2R,3R)-和(2S,3S)-2-甲基丁烷-1,2,3,4-四醇。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
