All three together now: Three‐component reactions of aldehydes, anilines, and α‐isocyanoacetamides in the presence of a catalytic amount of chiral phosphoric acid afforded the 5‐(1‐aminoalkyl)‐5‐aminooxazole 1 in excellent yields and moderate to good enantiomeric excess (see scheme).
现在这三者合在一起:醛,苯胺和α-异氰基乙酰胺的三组分反应,在催化量的手性磷酸的存在下,以优异的收率和中等至良好的产率提供了5-(1-氨基烷基)-5-氨基恶唑1。对映体过量(见方案)。
