Copper-catalyzed synthesis of heterocycle derivatives: use of β-enaminones
No full textThe use of β-enaminones in synthesis is a subject of great current interest, mostly because of their electronic properties. An appropriate design of the starting β-enaminone could allow for obtaining several classes of heterocyclic derivs. through base- or transition metal-catalyzed reactions. E.g., preparation. of a β-enaminone by reaction of 2-BrC6H4COC≡CPh, followed by addittion of CuI, K2CO3, and DMEDA in DMSO, gave 88% 4-quinolone derivative (I)

No full textParallel Palladium-Catalyzed Synthesis of Carboxylic Acids from Aryl Iodides, Bromides, and Vinyl Triflates Using Acetic Anhydride and Formate Anion as an External Condensed Source of Carbon Monoxide
Full text linkAryl iodides, bromides and vinyl-triflates are usually converted in high to excellent yields into the corresponding carboxylic acids through a parallel palladium-catalyzed hydroxycarbonylation using lithium formate and acetic anhydride as external condensed source of carbon monoxide
