Addition of dimethyl phosphite to the triple bond of dimethylacetylene-dicarboxylate by conventional routes or assisted by microwaves leads predominantly to the meso form of 2,3-bisphosphonosuccinic acid hexamethyl ester [(CH3O)(2)(O)P-CH-COOCH3](2). Molecular structure and dominant rotamer were deduced from multinuclear P-31(H-1)-, C-13(H-1)-, H-1-, H-1(P-31)-NMR studies on ABX and [AM(3)R(3)X](2)+Z(6) spin systems. Vicinal coupling constants (3)J(PP), (3)J(PH), and (3)J(HH) were used as stereochemically relevant parameters to deduce rotamer preferences via Karplus-type relationships.
