The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (S)-3-(Piperidin-2-yl)pyridine( cas:494-52-0 ) is researched.Quality Control of (S)-3-(Piperidin-2-yl)pyridine.Scharenberg, Friederike; Stegemann, Thomas; Cicek, Serhat Sezai; Zidorn, Christian published the article 《Sequestration of pyridine alkaloids anabasine and nicotine from Nicotiana (Solanaceae) by Orobanche ramosa (Orobanchaceae)》 about this compound( cas:494-52-0 ) in Biochemical Systematics and Ecology. Keywords: Orobanche Nicotiana anabasine nicotine anatabine nornicotine root Germany. Let’s learn more about this compound (cas:494-52-0).
Plants of the root holoparasite Orobanche ramosa L. and four of its potential host species, Nicotiana glauca Graham, Nicotiana rustica L., Nicotiana sylvestris Speg. & S.Comes, and Nicotiana tabacum L., grown in the greenhouse in Kiel/Germany, were analyzed for their contents of pyridine alkaloids anabasine (1) and nicotine (2). All investigated samples contained both alkaloids in different amounts The distribution of the alkaloids in the various plant organs of Nicotiana differed significantly between the species. The alkaloid contents of the Orobanche samples relative to the alkaloid contents of the roots of the resp. host plants varied between 3.47 ± 1.08 and 28.8 ± 37.5%. Orobanche plants drain water and crucial nutrients from their hosts; also, some examples for the sequestration of specialized natural products have been reported. O. ramosa is not able to synthesize pyridine alkaloids anabasine (1) and nicotine (2) itself; therefore, the present study proves the sequestration of pyridine alkaloids by O. ramosa from the four investigated Nicotiana host species.
