Synthesis of Novel Fluorinated Bisphosphonates and Bisphosphonic Acids
摘要:
The synthesis of novel fluorinated bisphosphonates with two, three, four, and six difluoromethylene groups (1a, 1b, 8, 12, and 15) (44-78%) by different approaches is described. The bisphosphonates were converted to the corresponding trimethylsilyl esters which on treatment with deionized water afforded the respective bisphosphonic acids (6, 10, and 14) in good yields.
A new synthetic route to perfluoroalkylidene-α,ω-bisphosphonates
摘要:
The UV irradiation of a mixture of (EtO)(2)POP(OEt)(2) and I(CF2)(n)I (n = 3,4, 6) or I(CF2)(n)P(O)(OEt)(2) (n = 1, 2) results in the corresponding bisphosphonites or mixed phosphonite-phosphonates, respectively: which on oxidation by Me(3)COOH afforded the perfluoroalkylidene-alpha,omega-bisphosphonates in 64-77% isolated yields.
