The Mannich reaction of 1-(3-aminobenzyl) tetrahydroisoquinolines (Va and Vb) with 36% formaldehyde solution in ethanol afforded the corresponding aminoprotoberberines (VIa and IXa, VIb and IXb), formed by the cyclization at the position para and ortho to the amino group and a modified synthesis of 9,10-disubstituted and 9,10,11-trisubstituted protoberberines was accomplished by the reduction or thermal decomposition of the diazonium salts of the aminoprotoberberines.
