  Application of the BHQ benzannulation reaction to the synthesis of benzo-fused coumarins

  摘要：

  A new approach to the synthesis of the 6H-benzo[d]naphthal[,2-b]pyran-6-one ring system present in the gilvocarcin family of antibiotics is described. The key feature of this approach is the application of a new benzannulation strategy (the 'BHQ Reaction') whereby readily available ortho-allylaryl trichloroacetates are transformed into naphthalene derivatives via a cascade of reactions involving an initial ATRC reaction followed by the extrusion of CO2.

  Microwave-promoted novel and efficient one-step parallel synthesis of dibenzopyranones and heterocyclic analogues from bromo arylcarboxylates and o-hydroxyarylboronic acids via Suzuki−Miyaura cross coupling reaction is described. Spontaneous lactonization gave dibenzopyranones and heterocyclic analogues bearing electron-donating and -withdrawing groups on both aromatic rings in good to excellent yields

  An effective and eco-friendly oxidation method for the synthesis of benzo[c]chromen-6-ones is described. The condition constitutes 6 molar ratio TBHP, catalytic KI and pyridine in acetonitrile as the solvent. Altogether, 16 structurally diverse substituted benzo[c]chromen-6-ones were prepared through this protocol from corresponding benzo[c]chromenes in excellent yields.
