  This application relates to the design and synthesis of new chiral imines reagents which can be utilized for the synthesis of chiral drugs and their precursors. It describes the design of the free NH2-group-attached chiral phosphoramides, a chiral N-phosphonimines and the methods for forming the same. The free NH2-group-attached chiral phosphoramides, having the structure of formula (I): wherein R1 and R2 are independently any organic groups. The synthesis of N-phosphoramides was performed starting from chiral 1,2-diamines via the following steps: N,N′-dialkylation consisting of aldehyde condensation and reduction, cyclization with phosphoryl halide, substitution of halide with azide anion and hydrogenation of azides. The N-phosphonyl imines are synthesized by condensation of N-phosphoramides with aldehydes. Quantitative yield was obtained for each of the four steps without special purification. All precursors were obtained as white solids. It should be addressed that after each application reaction of N-phosphonyl imines, N,N′-dialkyl vicinal diamine auxiliaries can be recovered quantitatively with one-time extraction using n-butanol and re-used.

  该应用涉及新手性亚胺试剂的设计和合成，可用于合成手性药物及其前体。它描述了自由NH2基固定的手性磷酰胺、手性N-膦酰亚胺的设计以及其制备方法。自由NH2基固定的手性磷酰胺的结构式如下：其中R1和R2是任意的有机基团。N-磷酰胺的合成是从手性1,2-二胺开始进行的，经过以下步骤：醛缩和还原的N,N'-二烷基化，磷酰卤素的环化，卤素的取代反应和氮化物的氢化反应。N-膦酰亚胺是通过N-磷酰胺与醛的缩合反应合成的。每个步骤都可以获得定量收率，无需特殊纯化。所有前体均为白色固体。需要指出的是，在每次应用N-膦酰亚胺反应后，N,N'-二烷基邻二胺辅助剂可以使用正丁醇一次性萃取并再次使用。
