  • Novel, cyclic and bicyclic 1,3-diols as catalysts for the diethylzinc addition to aldehydes
    作者:Ian Sarvary、Yiqian Wan、Torbjörn Frejd
    DOI:10.1039/b110082n
    日期:2002.2.22
    A number of optically pure 1,3-diols have been synthesized and used as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes. Enantiomeric excesses of up to 92% of (R)-1-phenylpropan-1-ol were obtained with anisylbicyclo[2.2.2]octanediol (14) as a catalyst. Using 2-picolylbicyclo[2.2.2]ocatanediol (16) as the catalyst resulted in a reversal of the stereoselectivity, yielding (S)-1-phenylpropan-1-ol in 83% ee. A pronounced positive non-linear effect was observed when varying the enantiomeric purity of catalyst 14.
    合成了一些光学纯的1,3-二醇,并将其用作对映选择性添加二乙基于芳香醛的催化剂。以苯基双环[2.2.2]八醇(14)作为催化剂时,获得了高达92%的(R)-1-苯基丙醇的对映体过量。使用2-吡啶基双环[2.2.2]八醇(16)作为催化剂则使立体选择性发生了逆转,得到了83%对映体过量的(S)-1-苯基丙醇。当改变催化剂14的对映体纯度时,观察到了明显的正非线性效应。
  • Bicyclo[2.2.2]octane-derived chiral ligands—synthesis and application of BODOLs in the asymmetric reduction of acetophenone with catecholborane
    作者:Annika Friberg、Ian Sarvary、Ola F. Wendt、Torbjörn Frejd
    DOI:10.1016/j.tetasy.2008.07.006
    日期:2008.8
    An improved synthetic route to the bicyclo[2.2.2]octane-2,6-diol ligands (2,6-BODOLS) allowed an increased structural variation of the ligand side-arm. The addition of aromatic or vinylic Grignard reagents to hydroxyketone 1 was highly selective and ligands 3f-3I were isolated in 84-97% yield. The addition of alkyl Grignard reagents containing beta-hydrogens resulted in lower yields (13-71%) due to competing ketone reduction. A number of 2,5-BODOLs were synthesized using a similar methodology. The ligands, together with Ti(OiPr)(4), were tested in the asymmetric reduction of acetophenone with catecholborane (up to 98% ee). 1-Naphthyl-BODOL 3i was employed as an allylboration reagent to benzaldehyde together with Sc(OTf)(3), resulting in (1S)-1-phenyl-3-buten-1-ol in 80% ee.
