Abstract
AbstractThe Pd(OAc)2‐induced carbonylation of alkoxy‐substituted 1‐amino‐2‐phenyltetralins and 1‐amino‐2‐phenylnaphthalenes was examined to provide the benzo[c]phenanthridine ring system. The carbonylation of substrates containing methylenedioxy groups gave oxysanguinarine and oxyavicine. The tetramethoxy derivatives gave O‐methyloxyfagaronine. The substrate with a benzyloxy group afforded a known synthetic precursor to the antileukemic alkaloid, fagaronine.
