Description and Uses
The alkaloids found in tobacco smoke may be separated into those which are volatile in steam and those which are non-volatile. Myosmine occurs in the former group and, although only present in small quantities, is the most fully investigated of these bases. The alkaloid is normally obtained as an oily liquid which may be crystallized. It is optically inactive and readily soluble in light petroleum or Et20. It forms a hydrochloride as a microcrystalline powder which, on sublimation yields colourless rods, m.p. ISS-8°C. The dihydrochloride, also a microcrystalline powder, yields colourless needles on sublimation, m.p. 1S0- 17 Soc. The base also furnishes a dipicrate, m.p. 182-3°C (dec.) and a dipi_x0002_crolonate, m.p. 204°C (dec.). On dehydrogenation it gives 2-(3'-pyridyl)-pyrrole (picrate, m.p. 200°C) identical with that obtained in a similar manner from nornicotine. According to Woodward and his colleagues, the alkaloid is one of several products formed when nicotine is dehydrogenated over prepared quartz at S70°C. It is readily hydrolyzed in H20 to yield 3-pyridyl-r-aminopropyl ketone, forming a crystalline phenylhydrazone, m.p. 20l-2°C.
