Synthesis of Annulated Anthracenes, Carb­azoles, and Thiophenes Involving Bradsher-Type Cyclodehydration or Cycli­zation-Reductive-Dehydration Reactions

A conventional BF3·OEt2‐mediated Bradsher‐type cyclodehydration of 2‐arylmethyl benzaldehydes in CH2Cl2 at room temperature gave polycyclic aromatic and heteroaromatic compounds. Alternatively, these compounds could be synthesized in better yields from 2‐arylmethylbenzoic acids by triflic‐acid‐media...
