Disclosed is a process for producing an optically active phosphorus compound having an R- or S-type absolute configuration on phosphorus in a simple manner and at high efficiency, while avoiding racemization.
An optically active phosphorus compound having an R- or S-type absolute configuration on phosphorus represented by the general formula (III) can be produced by reacting an optically active phosphorus compound having an R- or S-type absolute configuration on phosphorus represented by the general formula (I) with a metal compound represented by the general formula (II) and water. (I) wherein R
1
represents a hydrogen atom, analkyl group, a cycloalkyl group, an aralkyl group or an aryl group; and R
2
represents a hydrogen, an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, alkenyl group, an alkoxy group, an aryloxy group, a heterocyclic ring residue or a silyl-containing group. R
3
M (II) wherein R
3
is the same as R
2
; and M represents a lithium or magnesium halide MgX (X═Cl, Br or I). (III) wherein R
2
and R
3
are as defined above.
揭示了一种在简单且高效的情况下产生具有磷上的R型或S型绝对构型的光学活性磷化合物的方法,同时避免了消旋化。通过将具有磷上的R型或S型绝对构型的光学活性磷化合物(由通式(I)表示)与由通式(II)表示的金属化合物和水反应,可以生产具有磷上的R型或S型绝对构型的光学活性磷化合物(由通式(III)表示)。其中,通式(I)中R1代表氢原子、烷基、环烷基、芳基或芳基;R2代表氢、烷基、环烷基、芳基、芳基、烯基、烷氧基、芳氧基、杂环残基或含硅基团。通式(II)中R3与R2相同;M代表锂或镁卤化物MgX(X=Cl、Br或I)。通式(III)中R2和R3如上定义。
