## Abstract magnified image The reaction of 2,3βbutanedione, ethyl pyruvate, and phenylglyoxal with Ξ²βnitrostyrene and Lβproline in isopropanol at room temperature gives substituted pyrrolizidines, as a result of oneβpot three component reaction. On the contrary, a spiropyrrolizidine is formed fro
A I3C NMR method has been developed for obtaining simultaneously structural and quantitative information on mixtures of pyrrolizidine alkaloids from Senecio vulgaris L. (Compositae). The samples contained seneciphylline, senecionine, retrorsine and the corresponding E geometrical isomers, spartioidi
