Quinolizidines (I, II; R = -COOC2H5, -COOH, -CN,primary or secondary methyleneamino, methyleneamido; R = N-CO-NH-CH2 or N-CO-) were prepd. Thus, tryptomaine reacted with methyl - chloride and 2-cyano-2-ethyl-5-chlorovaleroilchloride to give 3-[2'-(2"-cyano-2"-ethyl-5"-chlorovaleroilchloride, which was reacted with tetrahydrofuran and 5-butanol to give 1-[(2'-indo-yl-ethyl)-3-ethyl-3-cyano -2-piperidone, which was reacted with phosphorylchloride to give 1-ethyl-1-cyano-5,12b-dihydro-indolo(2,3-a)-quinolidinumchloride.
