Abstract:
Systematic SAR studies of the different regioisomers and homologues of the spiro(indane-1,4-piperidine) moiety in the growth hormone secretagogue L-162,752 are presented. Among them, spiro(3H-1-benzopyran-2,3-piperidine) was found to afford secretagogues with low nanomolar in vitro activity.
