which demand for both good diastereo- and enantioselectivity. As part of our continuous effort to explore the unique catalytic activities of amino acid salts in the asymmetric synthesis, herein, we wish to report an amino acid salt catalyzed direct aldol reaction between hydroxyacetone and α-keto esters, which afforded the 1,2-diols with a quaternary carbon center in high diastereo- and enantioselectivities
具有季碳中心的对映体富集 1,2-二醇在制备天然和生物活性化合物方面具有巨大潜力,但仍然具有挑战性的合成目标,需要良好的非对映选择性和对映选择性。作为我们不断努力探索氨基酸盐在不对称合成中的独特催化活性的一部分,在此,我们希望报告一种氨基酸盐催化羟基丙酮和 α-酮酯之间的直接羟醛反应,它提供了 1,2-具有高非对映选择性和对映选择性的季碳中心的二醇。
