[Syntheses of 14C-1-erythro-norephedrine and its N-substitution products 14C-oxyfedrine and 14C-D 13,625].
Starting from 14C-benzene (--)-erythro-norephedrine (14C-1-norephedrine) was obtained in a 6-step synthesis. 14C-1-Norephedrine functioned as an intermediate for the synthesis of the carbon labelled partial beta-agonist oxyfedrine hydrochloride (ildamen) and the new positive inotropic agent D 13 625 (alifedrine hydrochloride).
