A novel series of aryl 1-but-3-ynyl-4-phenyl-1,2,3,6-tetrahydropyridines with dopaminergic activity is described. The structure-activity relationships of this series were studied by synthesis of analogs and evaluation of their affinities for the dopamine (DA) D2 receptor and inhibition of locomotor activity (LMA)

Pharmacologically interesting lycorines were obtained by a short, efficient method based on an intramolecular Diels-Alder reaction between an alpha-pyrone and an alkyne, followed by loss of CO(2) in a retro Diels-Alder reaction. The cyclization precursors (pyrones 9) were obtained in
