(R)-1-((R)-6-fluorochroman-2-yl)ethane-1,2-diol, (R)-1-((S)-6-fluorochroman-2-yl)ethane-1,2-diol and (S)-6-fluoro-2-((R)-oxiran-2-yl)chroman, which have been used as late-stage intermediates for the asymmetric synthesis of the antihypertensive drug (S,R,R,R)-nebivolol. Noteworthy is that a large number of racemic and asymmetric syntheses of nebivolol and their intermediates have been described in the literature, however
尽管在无环分子和饱和杂环的合成中利用Sharpless不对称二羟基化作为手性的来源是巨大的,但其对手性苯并环化杂环的合成效用却相对有限。因此,在寻找Sharpless不对称二羟基化衍生二醇在苯并环杂环合成中的更广泛应用时,我们在此报告了我们在(R)-1-((R)-6-fluorochroman-2)不对称合成中的研究。 -基)乙烷-1,2-二醇,(R)-1-(((S)-6-氟苯并茂-2-基)乙烷-1,2-二醇和(S)-6-氟-2-((( R)-环氧乙烷-2-基)苯并二氢吡喃已用作抗高血压药(S,R,R,R)-奈比洛尔的不对称合成的后期中间体。
