A new, one-pot, multicomponent synthesis of 5-aza-9-deaza-adenines under microwave irradiation
A new, practical, three-component method for the synthesis of 5-aza-9-deaza-adenines is developed. Aminopyrazoles react in a one-pot fashion with triethyl orthoformate and cyanamide under microwave irradiation affording 5-aza-9-deaza-adenines in good yiel

Novel potent neuropeptide Y Y5 receptor antagonists: Synthesis and structure-activity relationships of phenylpiperazine derivatives
A series of phenylpiperazine derivatives were synthesized and evaluated for their neuropeptide Y (NPY) Y5 receptor antagonistic activities. The benzindane portion of 2 was replaced by 1-phenylpiperazine, resulting in novel urea derivative 3f. Subsequent optimization of the phenylpiperazine template by substitution of the phenyl moiety resulted in a series of (2-methanesulfonamidephenyl)piperazine derivatives that showed potent binding affinity and antagonistic activity for the Y5 receptor.
