Novel and efficient one-step parallel synthesis of dibenzopyranones via Suzuki-Miyaura cross coupling.

ABSTRACT: 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.
