Geometrical isomers of 2-hydroxy-2-thio-4-methyl-1,3,2-dioxaphosphorinan (I) and 2- hydroxy-2-seleno-4-methyl-1,3,2-dioxaphosphorinan (V) have been prepared stereospecifically by : (a) demethylation of cis- and trans-2-methoxy-2-thio-4-methyl-1,3,2-dioxaphosphorinan (IV) and 2-methoxy- 2-seleno-4-methyl-1,3,2-dioxaphosphorinan (VI) with trimethylamine, and (b) addition of sulphur and selenium to geometrical
2-羟基-2-硫代-4-甲基-1,3,2-二氧杂磷酰胺基(I)和2-羟基-2-硒代-4-甲基-1,3,2-二氧杂磷酸酯(V)的几何异构体立体定向地通过以下方法制备:(a)顺式和反式-2-甲氧基-2-硫代-4-甲基-1,3,2-二氧杂磷酰胺(IV)和2-甲氧基-2-硒代-4-甲基-1的甲基化,3,2-二氧杂磷酰胺(VI)与三甲胺,和(b)将硫和硒加到2-氢-2-氧代-4-甲基-1,3,2-二氧杂磷酰胺(VIII)的几何异构体中。已经证明,将硫和硒添加到P(O)H基团中会继续保持P原子上的构型。
