Trialkyl phosphites induced a carboncarbon condensation reaction inp-nitrobenzaldehyde and ino-nitrobenzaldehyde, at 20°. The products were 2,2,2-trialkoxy-4,5-di nitrophenyl)1,3,2-dioxaphospholanes. Both diastereomers at carbon were produced; the major isomer had themeso-configuration. The phospholanes were hydrolyzed to glycol phosphotriesters of known configuration. The phospholanes were converted
亚磷酸三烷基酯在20°下在对硝基苯甲醛和邻硝基苯甲醛中引起碳缩合反应。产物为2,2,2-三烷氧基-4,5-二硝基苯基)1,3,2-二氧杂膦。产生了两种碳的非对映异构体。主要异构体具有内消旋构型。将膦酸酯水解成已知构型的二醇磷酸三酯。通过热醇将膦酸酯转化成已知构型的二硝基二苯乙烯氧化物。米-硝基苯甲醛,氯苯甲醛和具有电子释放基团的芳族醛在20°下无法与亚磷酸三烷基酯反应。这些反应过程的先前报告显示是错误的。
