A synthesis of (2S,3S,7S)-3,7-dimethylpentadecan-2-yl acetate () and propionate () is described. (2S)-2-Methyldecan-1-yl lithium () was reacted with (3S,4S)-3,4-dimethyl-γ-butyrolactone () to yield the ketoalcohol which upon Huang-Minlon reduction furnished (2S,3S,7S)-3,7-dimethylpentadecan-2-ol (). Acylations gave the esters and . The (2S)-2-methyldecan-1-yl lithium was obtained via asymmetric synthesis
描述了(2 S,3 S,7 S)-3,7-二甲基十五烷-2-基乙酸酯()和丙酸酯()的合成。使(2 S)-2-甲基癸基-1-基锂()与(3 S,4 S)-3,4-二甲基-γ-丁内酯()反应生成酮醇,通过黄敏隆还原法制得(2 S,3 S,7 S)-3,7-二甲基十五烷-2-醇()。酰基化得到酯和。通过不对称合成获得(2S)-2-甲基癸-1-基锂。手性内酯由(2S,3S)-反式-2,3-环氧丁烷和丙二酸二甲酯获得。
