Takahashi, Ikko published the artcileBronsted acid-catalyzed tandem cycloaromatization of naphthalene-based bisacetals: selective synthesis of ortho-fused six-hexagon benzenoids, Quality Control of 152873-79-5, the publication is Chemistry Letters (2017), 46(3), 392-394, database is CAplus.
Naphthalenes bearing two acetal moieties connected by a methylene-2,1-phenylene group underwent regioselective tandem cycloaromatization using a catalytic amount of trifluoromethanesulfonic acid in 1,1,1,3,3,3-hexafluoropropan-2-ol. Five substrates were successfully employed in this protocol to afford ortho-fused six-hexagon benzenoids with high selectivities and in excellent yields.
