Abstract
The invention relates to a compound of the formula (II) ##STR1## and the corresponding isomers and salts, in which formula: a and b are integers which independently of one another can assume the values 0 or 1, PA0 R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent, independently, a hydrogen atom, a linear or branched C.sub.1 -C.sub.6 -alkyl radical or a C.sub.1 -C.sub.4 -alkoxy radical, PA0 R.sub.6 represents a C.sub.1 -C.sub.6 -alkyl radical, PA0 R.sub.5 and R.sub.12 represent a hydrogen atom or a C.sub.1 -C.sub.4 -alkyl radical, with the proviso that R.sub.5 cannot represent hydrogen if a=b=0 and PA0 R.sub.11 has various meanings. These compounds have useful dermatological properties.
