There are disclosed compounds of general formula (I). Y is a linking group, chosen from a wide range, but including -COO-, -CH2COO-, -CONH-, -CON(CH3)-, -CH2CONH-, -SO2NH-, -SO2N(CH3)- and -PO(OC2H5)NH-. W is an alkylene chain. A is a substituted phenyl group or a benzofuran or benzodioxan group. R and R1 may have many values, but R is preferably a bulky group. These compounds and their prodrugs, enantiomers, diastereoisomers, N-oxides and pharmaceutically acceptable salts block alpha 1A-adrenergic receptors and are thus useful for the prevention of contractions of the prostate, urethra and lower urinary tract, without affecting blood pressure.
