Abstract
The invention relates to new spirocyclic aminoacid derivatives of the formula I ##STR1## in which m denotes 1 or 2, n denotes 0 or 1, R denotes hydrogen, alkyl or aralkyl, R.sup.1 denotes hydrogen or alkyl which can be optionally substituted by amino, acylamino or benzoylamino, alkenyl, cycloalkyl, cycloalkenyl, cycloalkylalkyl, aryl or partially hydrogenated aryl, each of which can be substituted by alkyl, alkoxy or halogen, arylalkyl or aroylalkyl, both of which can be substituted as defined above in the aryl radical, an S- or O- and/or N-heterocyclic radical or a side chain of an .alpha.-aminoacid, R.sup.2 denotes hydrogen, alkyl, alkenyl or aralkyl, Y denotes hydrogen or hydroxyl, Z denotes hydrogen, or Y and Z together denote oxygen and X denotes alkyl, alkenyl, cycloalkyl, aryl, which can be monosubstituted, disubstituted or trisubstituted by alkyl, alkoxy, hydroxyl, halogen, nitro, amino, alkylamino, dialkylamino and/or methylenedioxy, or 3-indolyl, processes for their preparation, agents containing them and their use and new spirocyclic aminoacids as intermediates and a process for their preparation.
