Abstract
The reactions of methoxy dioxaphospholan and corresponding hydrogen phosphonate 1 with (MeN = CHCl)Cl, (MeO)2CHNMe2 and MeOCH2NMe2 have been studied.
These reactions lead either to amino diphosphonate 5 or to amino phosphonate 3 and phosphate 2. The hydrolysis and methanolysis reactions of 5 are also presented.
