An improved protocol for the Pd-catalyzed alpha-arylation of aldehydes with arylhalides has been developed. The new catalytic system allows for the coupling of an array of substrates including challenging electron-rich aryl bromides and less reactive aryl chlorides. The utility of this method has been demonstrated in a new total synthesis of (+/-)-sporochnol.

Alkylation of aluminum phenolate by nerol and of phenol by nerol in the presence of the organoaluminum compounds aluminum phenolate and aluminumisopropylate was studied. The reaction products were isolated and characterized. Several features of the process were determined. It was found that ortho-substitution of the aromatic ring occurred primarily. In several instances nerol was cyclized. The fraction
