    摘要: Compounds of the formula (I) in which: R is a possibly substituted amino group of the general form --NR.sub.1 R.sub.2, in which R.sub.1 and R.sub.2 are independently hydrogen, lower alkyl, lower alkenyl or lower alkinyl, or R is a saturated, unsaturated or aromatic heterocyclic ring which may be mono or bi-substituted by lower alkyl or halogen; alk is a valency bond, a methylene, a saturated or unsaturated, straight or branched-chain alkylene chain with 2-6 carbon atoms; and R.sup.3, R.sup.4, R.sup.5 are independently hydrogen, lower alkyl or benzyl; and their pharmacologically acceptable salts and enantiomers where, if R.sup.3 .dbd.R.sup.4 .dbd.R.sup.5 .dbd.CH.sub.3 and alk is a valency bond, R may not be the dimethyl amino group. Process for their production and medicaments containing these compounds, for the treatment of calcium metabolic complaints.
