2,7,8-Trioxa-1-phosphabicyclo[3,2,1]octane and its 4,4-dimethyl derivative have been prepared by transesterification. Both compounds undergo stereospecific ring opening when treated with benzyl or triphenylmethyl chlorides, methyl toluene-p-sulphonate, N-chloropiperidine, or N-chloromorpholine. Attempts to prepare 2,6,7-trioxa-1-phosphabicyclo[2,2,1]heptane have been unsuccessful.
通过酯交换反应制备了2,7,8-三氧杂-1-膦双环[3,2,1]辛烷及其4,4-二甲基衍生物。当用苄基或三苯基甲基氯,甲苯-对-磺酸甲酯,N-氯哌啶或N-氯吗啉处理时,两种化合物都经历立体有择的开环。尝试制备2,6,7-三氧杂-1-磷酸双环[2,2,1]庚烷没有成功。
