Selective ring opening and subsequent organometallic addition to α,β-epoxy aldehydes is found to afford anti-syn 3-bromo-1,2-diols in high stereo and chemical yield. This sequence is utilized for the enantioselective synthesis of (2S,3R,4R)-2-amino-1-cyclohexyl-6-methylheptane-3,4-diol (an isomer of the Abbott amino diol).
发现选择性开环和随后对 α,β-环氧醛的有机金属加成以高立体和化学产率提供反合成 3-溴-1,2-二醇。该序列用于对映选择性合成 (2S,3R,4R)-2-amino-1-cyclohexyl-6-methylheptane-3,4-diol(Abbott 氨基二醇的异构体)。
