PEG-immobilization of cardol and soluble polymer-supported synthesis of some cardol-coumarin derivatives: preliminary evaluation of their inhibitory activity on mushroom tyrosinase.

In this work, the PEG-immobilization and the liquid phase synthesis of some coumarins derived from cardol are presented. Some preliminary results on their tyrosinase inhibitory activity are also included.

Tetrabromo hydrogenated cardanol: Efficient and renewable brominating agent.

2,4,4,6-Tetrabromo-3-n-pentadecyl-2,5-cyclohexadienone (TBPCO) has been synthesized and used as a new efficient, convenient, and environmentally friendly brominating agent.
