  醛的第一次直接和对映选择性交叉羟醛反应

  摘要：

  第一个使用非等价醛的对映选择性催化直接交叉羟醛反应已使用脯氨酸作为反应催化剂完成。醛醇供体（R1 = Me、n-Bu、Bn，91 至 >99%）和醛醇受体（R2 = I-Pr、I-Bu、c-C6H11、Et、Ph，97-99%）的结构变化ee) 是可能的，同时保持高反应效率（75-88% 产率）。重要的是，这种新的羟醛变体可以轻松对映选择性地获得广泛的 β-羟基醛，这些 β-羟基醛是聚酮化合物合成中有价值的中间体。

  日期：2002.6.1

  The first enantioselective catalytic direct cross-aldol reaction that employs nonequivalent aldehydes has been accomplished using proline as the reaction catalyst. Structural variation in both the aldol donor (R1 = Me, n-Bu, Bn, 91 to >99%) and aldol acceptor (R2 = I-Pr, I-Bu, c-C6H11, Et, Ph, 97-99% ee) are possible while maintaining high reaction efficiency (75-88% yield). Significantly, this new
