Araliphatylaminoalkanediphosphonic acids of formula ##STR1## wherein R.sub.1 is an aromatically substituted aliphatic radical, R.sub.2 is hydrogen or a monovalent aliphatic radical and alk is a divalent aliphatic radical, and their salts, exhibit a pronounced regulatory action on the calcium metabolism and can be used as medicaments for the treatment of diseases that are attributable to calcium metabolism disorders. They are prepared, for example, by reacting a compound of formula ##STR2## wherein X.sub.3 is a carboxy and R.sub.0 is a radical R.sub.2, with phosphorous acid and phosphorous trichloride and hydrolysing the primary product.
化学式为 ##STR1## 的Araliphatylaminoalkanediphosphonic acids,其中R.sub.1是芳香族取代的脂肪基,R.sub.2是氢或一价脂肪基,而alk是二价脂肪基,以及它们的盐,表现出显著的对钙代谢的调节作用,并可用作治疗与钙代谢紊乱有关的疾病的药物。例如,它们可以通过将化合物的公式 ##STR2## 与磷酸和三氯化磷反应,并水解初级产物来制备。
