ortho‐Aryl phenols, synthesized via protecting group free Suzuki–Miyaura coupling of ortho‐halophenols and arene boronic acids, undergo a cyclization to dibenzofurans via oxidative C–H activation. The reaction proceeds under microwave irradiation in short reaction times using catalytic amounts of Pd(OAc)2 without additional ligands.

Tandem reactions that involve chemoselective Knoevenagel/Perkincondensation–decarboxylation–Heck/Suzuki coupling or Heck–aldol sequences have been achieved. This enabled the first concise and efficient synthesis of several important hydroxy‐functionalized compound classes, such as stilbene–cinnamoylhybrids (potent protein tyrosine phosphatase1B inhibitors), cinnamoyl–cinnamic acid hybrids, asymmetric

The Mycobacteriumtuberculosis (Mtb) prokaryotic ubiquitin-like (pup) proteasomesystem is an attractive target for new drug development. In this study a screen was performed identifying Tyrphostins as low micromolar inhibitors of the Mtb protease Dop. To gain insight in the important functional aspects of these inhibitors, 25 new analogues were prepared and validated, in vitro. Several new compounds
