Abstract
The invention relates to novel compounds of the general formula (I), ##STR1## wherein R means hydrogen or a straight or branched chain C.sub.1-6 alkoxy group; PA0 R.sup.1 stands for hydrogen or a straight or branched chain C.sub.1-6 alkyl group; PA0 R.sup.2 represents hydrogen or a straight or branched chain C.sub.1-6 alkyl group; PA0 R.sup.3 means hydrogen, a straight or branched chain C.sub.1-6 alkyl group optionally substituted by one or two hydroxyl and/or one or two straight or branched chain C.sub.1-4 alkoxy group(s); or a C.sub.4-7 cycloalkyl group; PA0 R.sup.4 stands for hydrogen or a straight or branched chain C.sub.1-6 alkyl group optionally substituted by one or two hydroxyl and/or one or two straight or branched chain C.sub.1-4 alkoxy group(s); or a C.sub.4-7 cycloalkyl group; or PA0 R.sup.3 and R.sup.4 together with the nitrogen atom, to which they are attached form a 4 to 8-membered cyclic group of formula ##STR2## optionally substituted by one or two straight or branched chain C.sub.1-4 alkoxy and/or one or two straight or branched chain C.sub.1-4 alkyl group(s), where optionally an oxygen or sulfur atom or an N-R.sup.5 group may be substituted for a ring carbon atom…
