Abstract

Two new total syntheses of 1-methyl-1, 2, 3, 4-dihydronaphtho [1, 2-f] isoquinolines are based on the construction of their phenanthrene ring system by photochemically induced cyclization of N-{2-[(E)-2-phenyl-1-ethenyl] phenylethyl} acetamides or 1-methyl-5-[(E)-2- phenyl-1-ethenyl]-1, 2, 3, 4-tetrahydroisoquinolines.
