α,α'-(2,6-Piperidinediyl)bis(acetophenone) Usage And Synthesis
DescriptionThis alkaloid from Lobelia in/lata Linn, and L. sessili/lora was originally designated isolobelanine but later shown to be norlobelanine. It gives well_x0002_crystallized salts including the hydrochloride, m.p. 201-2°C; nitrate, m.p. 193°C (dec.); methiodide, m.p. 183-4°C and the N-benzoyl derivative, m.p. l25-6°C. The N-methyl compound is lobelanine (q.v.). On reduction it gives first norlobeline and finally norlobelanidine (q.v.).
