On the basis of pK measurements, 13C nmr, and chemical arguments, the zwitterionic structures 3 and 4 have been assigned to the two minor products obtained by sulfonating strychnine or brucine in water with a mixture of sulfur dioxide and manganese dioxide. The same reagent sulfonates the quaternary salts of strychnine and brucine to give betaines, but fails to sulfonate many other strychnine derivatives as well as a number of other alkaloids examined.
