A diastereoselective synthesis of 2,6-syn-disubstituted tetrahydropyrans has been developed based on the ability of furanyl-ether chiral centres to epimerise readily under acidic conditions. This novel methodology was applied to the synthesis of (+)-2-((2S,6S)-6-methyltetrahydro-2H-pyran-2-yl) acetic acid, a component of the African civet cat's glandular marking secretion.
基于呋喃基-醚手性中心在酸性条件下易于差向异构的能力,已经开发了2,6-syn-二取代的四氢吡喃的非对映选择性合成。这种新颖的方法应用于合成(+)-2-((2S,6S)-6-甲基四氢-2H-吡喃-2-基)乙酸,这是非洲猫猫的腺体标记分泌物的组成部分。
