Annulated arenes and hetarenes were prepared in good to very good yields by hydriodic acid/red phosphorus mediated reductive cyclization of 3-(hetero)aryl phthalides. The reductive cyclization also proceeded successfully with 2-aroylbenzoic acids and 2-aroylnaphthoic acids.
SYNTHESIS OF 2-ALKYL-9,10-ANTHROQUINONES
Bowlus, Stephen B.
, p. 391 - 396 (2007/10/02)
Heretofore unknown higher alkyl-9,10-anthraquinones have been prepared by reductive cyclization of the corresponding alkylbenzoylbenzoic acid with hydriodic acid-red phosphorous in acetic acid at 160 deg C, and oxidation of the dihydroanthracenes thus afforded.
