Abstract

Alkaloid-like oxidation products are obtained when a quaternary N-alkyl-1-benzyl-1,2,3,4-tetrahydroisoquinolinium salt of the formula <FORM:0997495/C2/1> where R represents an alkyl radical of up to 4 carbon atoms, R1, R2 and R4, the same or different, represent hydroxy groups or alkoxy groups of up to 4 carbon atoms, R3 represents a hydrogen atom, a hydroxy group or an alkoxy group of up to 4 carbon atoms and X represents a univalent anion, is subjected to mild oxidation in aqueous solution at a pH of from 4 to 10, said solution being 0.001 to 0.01 molar. The process is preferably carried out at 20 DEG to 90 DEG C. Oxidizing agents which may be used are all such agents which can be applied to an aqueous solution or suspension.
