Abstract
The novel derivatives correspond to the general formula II: ##STR1## in which: R.sub.1 R.sub.2 R.sub.3 and R.sub.4 represent identical or different groups which can each be a hydrogen or halogen atom or an alkyl group, alkoxy, or benzyloxy group and R is the residue of an R--CHO aldehyde selected from among linear or branched saturated aliphatic aldehydes including 1 to 4 carbon atoms or again represents the Z--CH.dbd.CH radical in which Z represents a hydrogen atom, a linear or branched saturated alkyl group, an aromatic nucleus or an aromatic heterocyclic nucleus or again R represents the radical HO CH.sub.2 (CH OH)n--in which n has the value of 3 or 4. The novel compounds have high solubility in water and antibacterial activity and potentiating power.
