The palladium-catalyzed cross coupling Heck reaction of tosylate (2) and methyl acrylate has been developed as an efficient method for carbon-carbon bond formation. The tosylate (2) was reacted with methyl acrylate using palladium acetate as catalyst to p

The copper-catalyzed conjugate addition of various Grignard reagents to polyconjugated enones (dienone and enynone derivatives) is reported. The catalyst system, composed of copper triflate and an NHC ligand, led to the unusual selective formation of the 1,4-addition products. This reaction allows for the creation of all-carbon chiral quaternary centers with enantiomeric excesses up to 99 %. The remaining unsaturation on the 1,4 adducts give access to valuable synthetic transformations. Copyright

Carbonyl conjugated vinylic selenides undergo 1,3 and 1,5-carbonyl transposition sequences through organometallic reagents addition reactions followed by acid hydrolysis.
Stereoselective Synthesis of Conjugated Dienones via the Palladium-Catalyzed Cross-Coupling Reaction of 1-Alkenylboronates with 3-Halo-2-alken-1-ones

The synthesis of conjugated dienones by means of palladium-catalyzed cross-coupling reaction between (E)-1-alkenyl-1,3,2-benzodioxaboroles or diisopropyl (Z)-1-hexenylboronate with 3-halo-2-alken-1-ones is described.
Reactions of 3-cyclo-2-hexenone with Carbonyl Compounds. Regio- and Chemoselective Condensations
Hatanaka, Yasuo,Kuwajima, Isao
, p. 1932 - 1934 (2007/10/02)
Under the influence of SnCl4 or trimethylsilyl iodide the title compound reacts with acetals or aldehydes at the γ-position to give the corresponding condensation products, whereas fluoride or base-mediated reactions take place at the α-position to afford
