Single enantiomers of (E)-1,5-diarylpentene-4,5-diols have been synthesised by Horner–Wittig elimination. The stereochemistry is controlled by an asymmetric dihydroxylation, and a stereoselective reduction of a β-keto phosphine oxide.
(E)-1,5-二芳基戊烯-4,5-二醇的单对映体通过霍纳-维蒂格消除反应合成。立体化学由不对称二羟基化反应和β-酮膦酸的立体选择性还原反应控制。
