A new synthetic method for enantioselective synthesis of syn or anti -3-amino-3-aryl-1,2-alkanediols via proline catalyzed α-aminooxylation of β-amino aldehydes are described. This methodology is successfully applied to a concise and protecting group-free asymmetric synthesis of (–)-cytoxazone, (+)- epi -cytoxazone and formal synthesis of N-thiolated 2-oxazolidinone.
描述了一种通过脯氨酸催化 β-氨基醛的 α-氨基氧化作用对映选择性合成顺式或反-3-氨基-3-芳基-1,2-烷二醇的新合成方法。该方法已成功应用于 (-)-胞恶酮、(+)- 表 - 胞恶唑的简洁且无保护基团的不对称合成和 N-硫醇化 2-恶唑烷酮的正式合成。
