This invention relates a to a series of heterocyclic substituted piperazines of Formula I
pharmaceutical compositions containing them and intermediates used in their manufacture. The compounds of the invention selectively inhibit binding to the &agr;-1a adrenergic receptor, a receptor which has been implicated in benign prostatic hyperplasia. As such the compounds are potentially useful in the treatment of this disease.

The synthesis of the 6-azabicyclo[3.2.1]octane ring system, via Dieckmann cyclization, is described. Ring closure involves reaction of a caprolactam enolate with a C-6 ester, the reactive axial conformation of which is promoted by the presence of an N-tert-butyloxycarbonyl group on the lactam nitrogen. The results will enable the synthesis of new bridged caprolactams for testing as antibacterials and
