Abstract
It all adds up: Straightforward access to 2-alkyl-substituted 1,3-diketones is provided by a regioselective addition of aldehydes to enones catalyzed by the ruthenium hydride catalyst [RuHCl(CO)(PPh3)3] (see scheme). The reaction involves a hydrometalation of the enone to form a metal enolate, a cross-aldol reaction to form an alkoxymetal species, and a subsequent β-metal hydride elimination.
