Synthesis of Allenes by Catalytic Coupling of Propargyl Carbonates with Aryl Iodides in the Presence of Diboron Species
Yang, Yuzhu,Szabó, Kálmán J.
, p. 250 - 255 (2016/01/15)
Bimetallic copper-/palladium-catalyzed multicomponent reaction of propargyl carbonates, aryl iodides, and diboron species was studied. This procedure can be used for synthesis of di-, tri-, and tetra-substituted allenes. Using diboronic acid, the reaction
Stereoselective synthesis of chiral 3-aryl-1-alkynes from bromoallenes and heterocuprates
Caporusso, Anna Maria,Zampieri, Alessia,Aronica, Laura Antonella,Banti, Donatella
, p. 1902 - 1910 (2007/10/03)
The synthesis of chiral 3-aryl-1-alkynes 3 via cross-coupling of 3-alkyl- and 3,3-dialkyl-1-bromo-1,2-dienes 1 and arylbromocuprates (RCuBr)MgBr-LiBr 2 was examined. With phenylcopper reagents and its para-substituted derivatives, as well as with 2-naphth
Coupling of chiral 1-bromo-1,2-dienes with zinc-based cuprates: A new procedure for the regio and stereoselective synthesis of functionalized acetylenic compounds
Caporusso, Anna Maria,Filippi, Sara,Barontini, Federica,Salvadori, Piero
, p. 1227 - 1230 (2007/10/03)
Zinc alkylcyanocuprates (Knochel reagents) are found to be active in the cross-coupling reaction with allenic bromides affording acetylenic products with a high regio and stereoselective 1,3-anti substitution. The coupling process, which has been successf
