Bicyclic aromatic cpds. of formula (I), their salts and chiral analogues, are new. R1 = H, -CH3, -CH2-O-R3, -CH2-O-CO-R4, -O-R5, -O-(CH2)m-(CO)n-R6, -CO-R7, -CO-O-R8 or -S(O)p-R9, R2 = H, halo, lower alkyl, -NO2, -O-COR4, -OR9 or -N(R9)R10, Ar = a gp. of formula (a)-(e), X = -O-, -S(O)t or -NR9-, Y, Z = -O-, -S(O)t or -CR11R12, but are not both -O- or -S(O)t, m = 1-3, n = 0 or 1, p = 0, 1-3, t = 0, 1 or 2; R3, R5, R9, R10, R11, R12 = H or lower alkyl, R4 = lower alkyl, R5 = lower alkyl or heterocyclic radical, R7 = H, lower alkyl or -N(R')R", R', R" = H, lower alkyl, mono- or poly-hydroxyalkyl, aryl (opt. substd.) or an aminoacid, sugar or peptide residue, or R'+R" = heterocyclic gp., R8 = H, 1-20C alkyl, alkenyl, mono- or poly-hydroxyalkyl, aryl or aralkyl (opt. substd.) or an aminoacid, sugar or peptide residue.
