subtype-selective estrogenreceptor (ER) ligands, we have examined various heterocyclic units as core structural elements. Here, we have investigated the fused, bicyclic pyrazolo[1,5-a]pyrimidine core, which is a system that allows for analogues to be readily assembled in a library-like fashion. This series of pyrazolo[1,5-a]pyrimidine ER ligands provided us with a new pharmacological profile for an ER ligand: compounds

solid-phase synthesis of 5-aminopyrazole has been developed and applied to the preparation of pyrazolo[5,1-d][1,2,3,5]tetrazine-4(3H)-ones. In this strategy, a one-pot reaction from 5-aminopyrazoles to the pyrazolo[5,1-d][1,2,3,5]tetrazine-4(3H)-ones which provided the compounds in good yields was demonstrated. Using this synthetic strategy, we prepared a representative set of 16 pyrazolo[5,1-d][1,2,3,5]tetrazine-4(3H)-ones

We have examined the pyrazolo[1,5-a]pyrimidine scaffold as a novel core structure for estrogenreceptorligands. Attachment of various substituents has helped to define the orientation of this heterocycle in the ligand-binding pocket as one in which a pendant phenol rather than the hydroxylpyrimidine serves as a mimic of the A-ring of estradiol.
