The synthesis of new derivatives of embelin, a natural inhibitor of X-linked inhibitor of apoptosis protein (XIAP) is described. The design of these new molecules involved introduction of aromatic groups directly linked to the benzoquinone core. To allow a large flexibility in the nature and the length of the added chain, the strategy involves first aSuzuki-Miyaura reaction with functionalized aromatics, yielding a first generation of molecules. Then, by appropriate use of the functional groups, a second generation of representative embelin derivatives was prepared.

Microwave induced selective bromination of 1,4-quinones and coumarins

Microwave irradiation accelerates the bromination of 1,4-quinones and coumarins with (i) bromide adsorbed on neutral alumina in 'dry media' and (ii) with iodine monobromide on acetic acid as compared to the reactions run at room temperature. Bromination takes place selectively at active quinonoid position in 1,4-quinones and at α,β-double bond in coumarins.
