[GRAPHICS]The synthesis of cribrostatin 6 (1) is described. A regioselective bromination, a biaryl coupling, and an intramolecular cyclization are the key steps in the synthesis.
An unprecedented AlCl3-mediated method has been developed involving aromatic CâH bond addition to an alkyne and heteroarylation of an arene in a single pot leading to densely functionalized novel olefins, e.g. 2-(2,2-diarylvinyl)-3-arylquinoxalines, as potential inhibitors of sirtuins.
