Beschreibung

This alkaloid from Senecio Jacobea was originally given the empirical formula ClsH2S0sN by Barger and Blackie but has since been shown to exist as the chlorine-containing compound. It has[α] D + 52.5° (CHCl3 ) and on hydrolysis yields retronecine and jaconecic acid, ClOH160 6, m.p. l83-4°C; [α]25D + 28.1 ° (EtOH). In this reaction, the chlorine is also lost by hydrolysis. The base forms a dihydrochloride, m.p. 204-5°C (dec.).
