Demethylation of Quinine Using Anhydrous Aluminium Trichloride
Journal of Mathematical and Fundamental Sciences, 2013 Quinine is a natural alkaloid having a methoxy group bound to quinoline ring and an allyl group bound to quinuclidine ring. Demethylation of quinine applying strong acid such as HBr or HI at high temperature was unsuccessful. The aim of this research was
