We synthesized the racemates of five presumed metabolites (1b-f) of (s)- (-)-N-tert-butyl-4,4-diphenyl-2-cyclopentenylamine hydrochloride (FK584, S(- )-1a), a novel agent for the treatment of overactive detrusor syndrome, in order to confirm the structures of the metabolites and also to evaluate their inhibitory activity against detrusor contraction. (±)-N-tert-Butyl-4-(4- hydroxyphenyl)- and 4-(4-hydroxy-3-methoxyphenyl)-4-phenyl-2-cyclopentenyl- amines (1b-e) were synthesized via 5-(4-methoxyphenyl)- and 5-(4-benzyloxy- 3-methoxyphenyl)-5-phenyl-2-cyclopenten-1-one (9g, h), respectively. Compounds 1b-f prepared in this study were identical with the metabolites in human urine in gas chromatography mass spectrometry and analytical HPLC. The inhibitory activity of compounds 1b-f against detrusor contraction in vitro induced by electrical field stimulation in guinea-pigs was less potent than that of FK584.

Reduction of sterically unbiased 2-phenyl-2-(4-X-phenyl)cyclopentanones 1 (X = NO2, Br, Cl, OCH3, OH, NH2) with either sodium borohydride in methanol or lithium borohydride in tetrahydrofuran at 0°C produced diastereomeric
