Uncatalyzed one-pot, three-component reactions of aldehydes, chiral α-methylamines, and dimethyl phosphite under solvent-free conditions were used for the diastereoselective synthesis of α-amino phosphonates. The reactions proceeded with extremely high efficiency under mild conditions and gave good yields and diastereoselectivities (70:30 to 93:7 dr). This approach could be useful for the large-scale
在无溶剂条件下,醛、手性 α-甲胺和亚磷酸二甲酯的未催化一锅三组分反应用于非对映选择性合成 α-氨基膦酸酯。该反应在温和条件下以极高的效率进行,并产生良好的产率和非对映选择性(70:30 至 93:7 dr)。这种方法可用于多种 α-氨基膦酸酯的大规模合成。
