Abstract
Treatment of 1-(3-benzyloxybenzyl)-1,2,3,4-tetra-hydroisoquinolines (1, 5 and 6) with hydrochloric acid in ethanol without formalin gave the corresponding phenolic isoquinolines (2, 8 and 9) and the tetrahydro-prbtoberberines (3, 11 and 12). The former products (2, 8 and 9) on photolysis also gave the tetrahydroproto-berberines (3, 11 and 12) together with the normal products, aporphines.
