effectively synthesize chiral α‐amino aldehydes, which have a wide range of potential applications in organic synthesis and medicinal chemistry, a highly chemo‐ and enantioselective hydrogenation of α‐formyl enamides has been developed, catalyzed by a rhodium complex of a P‐stereogenic bisphosphine ligand. Under different hydrogen pressures, the chiral α‐amido aldehydes and β‐amido alcohols were obtained
为了有效合成在有机合成和药物化学中具有广泛潜在应用的手性α-氨基醛,已开发出一种高化学和对映选择性的α-甲酰胺基氢化反应,该反应由P的铑配合物催化立体异构双膦配体。在不同的氢气压力下,获得的手性α-酰胺醛和β-氨基醇的收率高(97-99%),并且具有出色的化学选择性和对映选择性(ee高达> 99.9% )。氢化反应可以以克为单位进行,并具有高的底物/催化剂比(最高20000 S / C),并且氢化的产物被进一步转化为几种重要的手性产物。催化循环的计算给出了R /的清晰描述。S途径为对映选择性提供了合理的解释,并揭示了其他几个具体特征。
