As new compound, a series of 2-hydrocinnamoyl-1,3-cyclopentanedione derivative of the general formula: STR1 WHEREIN Ar stands for a mono-valent aromatic radical, for example, phenyl and 3,4-methylenedioxy-phenyl, substituted or unsubstituted, have been found to have an activity to inhibit the action of tyrosine hydroxylase and to be useful as hypotensive agent. These new compounds may be produced by condensing 2-acetyl-1,3-cyclopentanedione with an aromatic aldehyde of the formula Ar-CHO wherein Ar is as defined, according to Claisen-Schmidt condensation, followed by the hydrogenation of the condensation product obtained, or the new compounds may also be produced by reacting 2-acetyl-1,3-cyclopentanedione with an aromatic halide of the formula Ar-CH2 X wherein Ar is as defined and X is a halogen, for example, in liquid ammonia and in the presence of an alkali metal amide.
