The anabaseine derivatives 6‐methoxy‐7‐hydroxy‐1‐(pyridin‐3‐yl)‐3,4‐dihydroisoquinoline, 6,7‐dimethoxy‐1‐(pyridin‐3‐yl)‐1,2,3,4‐tetrahydroisoquinoline and 6,7‐dimethoxy‐1‐(piperidin‐3‐yl)‐1,2,3,4‐tetrahydroisoquino‐ line were prepared either by demethylation with HBr or by reduction with different reagents, NaBH 4 and H 2 /PtO 2 from 6,7‐dimethoxy‐1‐(pyridin‐3‐yl)‐3,4‐dihydroisoquinoline, as starting material. The structures have been fully assigned by the combination of one‐ and two‐dimensional experiments. Copyright © 2006 John Wiley & Sons, Ltd.
