Saturated nitrogencontaining heterocycles. 19. Catalytic reduction of 10- and 9,10-substitutedsym-octahydroacridinium salts
Abstract10-Methyl(phenyl)- and 9,10-diphenylperhydroacridines have been obtained by the catalytic reduction of 10- and 9,10-substituted sym-octahydroacridinium salts. Selective reduction of the furan ring occurred in the case of 9-(2-furyl)-10-phenyl-sym-octahydroacridinium perchlorate. The stereoisomeric composition of the reaction products has been established and a probable scheme for their formation has been proposed.
