We describe a novel method for the propargylation of a wide range of aldehydes and ketones catalyzed by titanocene(III) complexes under mild reaction conditions and compatible with many functional groups. Homopropargylic alcohols are obtained as the sole products even when ketones are used as starting materials, which is unusual in Barbier-type propargylations.
A synthesis of the abietane diterpenoid quinone (±)-royleanone via maleoylcobalt technology

(±)-Royleanone has been synthesized by rapid construction of a highly substituted quinone using maleoylcobalt complex technology followed by acid induced cyclization of the corresponding hydroquinone methyl ether onto a tethered enone. The synthesis was completed by straightforward functional group manipulations.
