Clear Light Red-Brown Oil | [Uses]
Nicotryrine is an alkaloid derived from the dehydrogenation of nicotine and its analog, nornicotine. An alkaloid occurring in cigaret smoke. | [Description]
The occurrence of this alkaloid in the cigar type of tobacco has been reported by
Wenusch and subsequently confirmed by Spath and Kesztler. It forms a colour_x0002_less oil when pure and yields crystalline salts and derivatives, e.g. the p1atinichloride, m.p. 158°C; picrate, m.p. 170-1 °c and the methiodide, m.p. 2l1-3°e.
It may also be prepared from nicotine by oxidation with silver oxide, silver
acetate or potassium ferricyanide. With Zn and HCI, the base is reduced to nicotine and 4:5-dihydronicotyrine, b.p. 244-6°C, yielding a dipicrate, m.p. l64°e.
In the presence of prepared Pt02, the latter may be further reduced to dihydrometanicotine, the dipicrate of which has m.p. 161-2°C. Nicotyrine may be converted directly into nicotine in one operation by controlled hydrogenation in the
presence on Pd-e | [Definition]
ChEBI: Nicotyrine is a member of pyridines. | [Synthesis Reference(s)]
