1H NMR and X-ray crystallography studies revealed that a CH-π and chelation control in aromatic aminoaldehydes (1–6) effects a highly diastereoselective addition to afford optically active syn-aminoalcohols (1a–6a). This methodology was applied to the synthesis of (−)-bestatin.
1 H NMR和X-射线晶体学研究表明,在芳族氨基醛(一个CH-π和螯合控制1 - 6)作用的高度非对映加成,得到光学活性的顺式氨基醇(1A -图6a)。将该方法应用于(-)-贝斯他汀的合成。
