Compounds of the formula I ##STR1## in which R.sub.1 is an aromatic radical, n is 0, 1, 2 or 3, X is an oxy group, a thio group which can be oxidized or an imino group which is unsubstituted or has aliphatic substituents, alk.sub.1 and alk.sub.2 are identical or different divalent aliphatic radicals, and R.sub.2 is hydrogen or a monovalent aliphatic radical and salts thereof have properties which regulate calcium metabolism and can be employed for the treatment of diseases connected with disturbances in this metabolism. They are prepared, for example, by reacting a compound of the formula ##STR2## in which X.sub.3 is carboxyl with a phosphorylating agent and hydrolysing the primary product.
公式I的化合物 ##STR1##中,其中R.sub.1是芳香基团,n为0、1、2或3,X是氧基、可氧化的硫基或未取代或带有脂肪基取代的亚胺基,alk.sub.1和alk.sub.2是相同或不同的二价脂肪基团,而R.sub.2是氢或一价脂肪基团。这些化合物及其盐具有调节钙代谢的特性,并可用于治疗与该代谢紊乱有关的疾病。例如,它们可通过将公式 ##STR2##中的化合物与磷酸化剂反应并水解初级产物来制备。
