In order to obtain ganglionic blocking agent, 9-oxocamphor oxime was reduced to 9-aminocamphor which was condensed with dialkylaminoalkyl chloride to form d-9-(dialkylaminoalkylamino) camphors (I to IV), which were further derived to their respective quaternary ammonium salts (VIII to XIII). 9-Aminocamphor was derived to 9-(chloroacetamido) camphor and 9-(chloropropionamido) camphor, which were reacted with secondary amines to form d-9-(dialkylaminoacylamino) camphors (XIV to XVIII). Quaternary ammonium salts (XIX to XXIII) of these compounds were also synthesized. Hypotensive effect was found in compounds (X) to (XII), (XXI), and (XXII).
