Abstract: Novel products of formula (I), their preparation, the pharmaceutical compositions which contain them and their use in the preparation of medicaments. ##STR1## In the formula (I), the following substituents are among the preferred: Ar represents a substituted or condensed phenyl radical or a polycyclic or heterocyclic aromatic radical, R represents a radical of general formula --(CH.sub.2).sub.m --X.sub.1 --(CH.sub.2).sub.n --Z in which X.sub.1 =single bond, O, S; m=0, 1; n=0, 1, 2; it being possible for the CH.sub.2 radicals to be substituted; Z represents carboxyl, COOR.sub.6 (R.sub.6 =alkyl), CON(R.sub.7)(R.sub.8) (R.sub.7 =hydrogen or alkyl and R.sub.8 =hydrogen, hydroxyl, arylsulphonyl, heterocyclyl, optionally substituted amino, optionally substituted alkyloxy or optionally substituted alkyl), PO(OR.sub.9).sub.2 (R.sub.9 =hydrogen or alkyl), an --NH--CO--T (T=hydrogen or optionally substituted alkyl) radical, or else--a ##STR2## radical, R.sub.1 and R.sub.

Abstract: Novel products of formula (I): ##STR1## preparation thereof and pharmaceutical compositions containing said products are disclosed. In formula (I), R is a group of formula --(CH.sub.2).sub.m --X.sub.1 --(CH.sub.2).sub.n --Z, where X.sub.1 is a simple bond or O or S, n is 0 or 1 and n is 0, 1 or 2, the CH.sub.2 groups being optionally substituted by carboxy, alkoxycarbonyl, carbamoyl, alkylcarbamoyl, dialkylcarbamoyl, amino, alkylamino or dialkylamino, and Z is carboxy, COOR.sub.4, where R.sub.4 is alkyl, or CON(R.sub.5)(R.sub.6), where R.sub.5 hydrogen or alkyl and R.sub.6 is hydrogen or optionally substituted alkyl, or else R.sub.5 is hydrogen or alkyl and R.sub.6 is hydroxy, optionally substituted alkoxy or amino, or PO(OR.sub.7).sub.2, where R.sub.7 is hydrogen or alkyl; or a group --NH--CO--T where T is hydrogen or optionally substituted alkyl; or else a group (a); R.sub.1 and R.sub.2 are hydrogen or halogen or optionally substituted alkyloxy or alkyl, or else R.sub.1 and R.sub.
