Provided are novel dialkyl (dialkoxyphosphinyl)methyl phosphates of formula ##STR1## which am useful as anti-inflammatory and anti-arthritic agents. The compounds are synthesized from the reaction of tetraethyl oxiranylidenebisphosphonate and unsubstituted or alkyl-amines. Representative compounds include 2-(benzylamino)-1-(diethoxyphosphinyl)ethyl phosphonic acid diethyl ester, 1-(diethoxyphosphinyl)-2-[2'-(1', 2', 3', 4'-tetrahydro)napthylamino]ethyl phosphonic acid diethyl ester, 2-(3-fluorobenzylamino)-1-(diethoxyphosphinyl)ethyl phosphonic acid diethyl ester, and 5,5 -dimethyl-2-[2-(3-fluorobenzyl)amino-1-[(5,5-dimethyl-1,3,2-dioxaphosphori nan-2-yl)oxy]ethyl]-1,3,2-dioxaphosphorinane P,2-dioxide.
提供的是式子为##STR1##的新型二烷基(二烷氧基膦基)甲基磷酸酯,它们可用作抗炎和抗关节炎药物。这些化合物是由四乙基氧环戊烷基双膦酸酯和非取代或烷基胺反应合成的。代表性的化合物包括2-(苄基氨基)-1-(二乙氧膦基)乙基膦酸二乙酯,1-(二乙氧膦基)-2-[2'-(1',2',3',4'-四氢萘基)氨基]乙基膦酸二乙酯,2-(3-氟苄基氨基)-1-(二乙氧膦基)乙基膦酸二乙酯和5,5-二甲基-2-[2-(3-氟苄基)氨基-1-[(5,5-二甲基-1,3,2-二氧磷杂环戊烷-2-基)氧基]乙基]-1,3,2-二氧磷杂环戊烷P,2-二氧化物。
