The present invention relates to (2S)-enantiomers of 2-aminoindan derivatives of formula I:and a novel process for the preparation of them.

Process to prepare 2-aminoindan derivatives

Compounds and their pharmaceutically acceptable salts suitable for treating central nervous system disorders associated with the dopamine D3 receptor activity of structural Formula I: ##STR1##

Aryl substituted bicyclic amines as selective dopamine D3 ligands

2-aminoindans as selective dopamine D3 ligands

A compound of Formula I ##STR1## or pharmaceutically acceptable salts of Formula I, where R.sup.1 is H, C.sub.1 -C.sub.3 alkyl, --(CH.sub.2).sub.n CONH.sub.2 where n is 2 to 6, (CH2).sub.n -1-(4,4-dimethylpiperidine-2,6-dione-yl), or cyclopropylmethyl; R.sup.2 is hydrogen, C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.8 cycloalkyl or combined with R.sup.1 to form a C.sub.3 -C.sub.8 cycloalkyl, C.sub.2 -C.sub.8 alkenyl, C.sub.2 -C.sub.8 akynyl, (CH.sub.2).sub.n --X--Ar where X is O, S, or NH, 3,3,3-trifluoropropyl, --(CH.sub.2).sub.m --R.sup.9 where m is 2 or 3 and R.sup.9 is phenyl, 2-thiophenyl or 3-thiophenyl; R.sup.3 is hydrogen, C.sub.1 -C.sub.3 alkyl, 2,2,2-trifluoroethyl, 3,3,3-trifluoropropyl, formyl, CN, halogen, CH.sub.2 OR.sup.2, C(O)C(O)OR.sup.1, C(O)CO NR.sup.1 R.sup.2, --(CH.sub.2).sub.q --NR.sup.1 R.sup.2 where q is 0 to 5, C.dbd.NOR.sup.2, 2(4,5-dihydro)oxazolyl, or COR.sup.10 where R.sup.10 is H, R.sup.1, NR.sup.1 R.sup.2 or CF.sub.3 ; R.sup.4 is hydrogen, C.sub.1 -C.sub.3 alkyl, cyclopropylmethyl, CF.sub.3, 2,2,2-trifluoroethyl, CN, CONR.sup.1 R.sup.2, .dbd.O, 2(4,5-dihydro)imidazolyl, 2(4,5-dihydro)oxazolyl, 2-oxazolyl, 3-oxadiazolyl, or 3,3,3-trifluoropropyl; R.sup.5 is hydrogen, R.sup.1, OCH.sub.3, C(O)CH.sub.3 or C(O)OR.sup.1 ; X is (a) a valence bond, (b) CH.sub.2, or (c) O, S or NR.sup.5 where R.sup.5 is H, C.sub.1 -C.sub.8 alkyl, C.sub.3 -C.sub.8 cycloalkyl, benzyl, COR.sup.6 where R.sup.6 is a C.sub.1 -C.sub.3 alkyl, phenyl, or CONR.sup.7 R.sup.8 where R.sup.7 and R.sup.8 are independently H or C.sub.1 -C.sub.3 alkyl; and Z is a hydrogen or halogen; provided that when X is CH.sub.2, at least one of R.sub.3 and R.sub.4 is other than hydrogen or C.sub.1 -C.sub.3 alkyl. The compounds of Formula I are suitable for treating disorders of the central nervous system, particularly as 5-HT.sub.1A receptor agonists.

Centrally acting 6,7,8,9-tetrahydro-3H-benz(e) indole heterocyclics

Indoletetralins having dopaminergic activity

This invention is therapeutically useful 2-aminotetralins and pharmaceutically acceptable acid addition salts thereof of the formula ##STR1## R, R.sub.1 to R.sub.5 and p are as defined in the specification, these compounds are useful to treat central nervous system disorders, hypertension, diabetes, sexual impotency and to control appetite.

Therapeutically useful 2-aminotetralin derivatives

This invention is therapeutically useful tetralins and pharmaceutically acceptable acid addition salts thereof of the formula I: ##STR1## wherein X is --(CH.sub.2).sub.n -- or --C(R.sub.1)(H)--; R is C.sub.1 -C.sub.8 alkyl; and R.sub.1 and R.sub.2 are the same or different and are selected from the group consisting of hydrogen, C.sub.1 -C.sub.8 alkyl, C.sub.2 -C.sub.8 alkenyl, C.sub.2 -C.sub.8) alkynyl, aryl and benzyl. These compounds are useful to treat central nervous system disorders and are unexpectedly resistant to metabolism by the liver and have superior oral plasma bioavailability.

Carboxamido-(1,2N)-carbocyclic-2-aminotetralin derivatives

A compound of Formula I ##STR1## or pharmaceutically acceptable salts of Formula I, where R.sup.1 is H, C.sub.1 -C.sub.3 alkyl, --(CH.sub.2).sub.n CONH.sub.2 where n is 2 to 6, (CH2).sub.n -1-(4,4-dimethylpiperidine-2,6-dione-yl), or cyclopropylmethyl;
