摘要:β-碘代Morita-Baylis-Hillman(MBH)加合物作为一种多官能团的手性砌块,是多种天然产物和药物分子的重要中间体.以课题组最近开发的An-PIQ为亲核催化剂,首次利用非酶亲核酰化动力学拆分的方法获得了一系列高光学纯β-碘代MBH加合物,S值最高可达165.该方法不仅解决了脂肪醛衍生的MBH加合物二级醇在动力学拆分中的低选择性问题,而且具有条件温和,较好的底物普适性,并能放大到克级规模等特点.
Chiral β-iodo Morita-Baylis-Hillman (MBH) adducts are important versatile synthetic building blocks for many nat-ural products and drug molecules. By using a recently developed acyl transfer catalyst An-PIQ, the kinetic resolutions of a series of β-iodo MBH adducts were investigated, providing the recovered alcohols in good yields with high enantioselectivities (up to 99.9% ee) and good selectivity factors (S up to 165). This method overcomes the issue of low selectivity confronted in the kinetic resolution of aliphatic aldehyde-derived MBH adducts as secondly alcohols, and features mild reaction conditions, broad sub-strate scope, and easy scaling-up to gram scale.
