New compounds of the general formula
wherein R' is hydrogen are described which possess a particularly high and selective affinity for β, receptors. Compounds of formula I wherein R' is an acyl group
can produce compounds of formula I wherein R' is H by biotransformation.
In formula I Ar is an aromatic or heteroaromatic group, defined by the formula
wherein m is an integer 0 or 1, n is an integer 1 to 3 provided that n is an integer 2 to 3 when m is 1 and R2 is a group -O-R3, -O-(CH2)qO-R3, a pyrazole group or a group
in which groups q is an integer 2 to 3 and R3 is a straight or branched alkyl group having 1-8 carbon atoms or a cycloalkylalkyl group having 4-8 carbon atoms, and X is N or C-R, wherein R is H, CN or OCH3. In the acyl group
p is an integer 0 or 1 and R4 is an aliphatic, cycloaliphatic or aromatic group, each of said group being optionally substituted or interrupted by heteroatoms.
Further described are methods for preparation of such compounds, pharmaceutical preparations thereof and methods for treatment employing the same.
