Syntheses of Allied Compounds of Lupine Alkaloids. V. Synthesis of 9-Azahexahydrojulolidine

抄録

9-Azahexahydrojulolidine (III) was prepared by saponification and decarboxylation of 2-cyanoperhydropyrido [3, 4, 5-i, j] quinolizine (II) with hydrochloric acid, obtained by reaction of 9-methyl-9-azahexahydrojulolidine (I) and cyanogen bromide. Series of these compounds was assumed to have the cis-quinolizidine ring and, in order to ascertain this assumption, (III) was converted to 9-azajulolidine (IV).
