The synthesis of a series of 2,3-diarylbenzo[b]furans starting from 1,2-diarylethanones and 1,2-dibromoarenes proceeds by means of both homogeneous and polymer-anchored palladium catalysts. This tandem process can be effectively halted at the C-arylation

A synthetic procedure, for the synthesis of a series of functionalized benzofurans 3–5 and benzonaphthofurans 6, starting from intermolecular O-alkylation of α-bromoaryl ketones 2 with potassium oxygenated phenoxides 1 followed by Ga(OTf)3-catalyzed direct intramolecular cyclodehydration of the resulting α-aryloxyaryl ketones, has been developed. The use of various metal triflates was investigated for a facile approach and efficient transformation. Pentacyclic benzophenanthrofurans 7 were prepared via photolytic annulations of 5.
