Mechanisms of double and single carbonylation reactions catalyzed by palladium complexes
Mechanisms of double carbonylation reactions catalyzed by palladium complexs to give a-keto amides and a-keto esters, stoichiometric double carbonylation of ally1 carbonates, and cyclization carbonylation . of 3-butenoic acid to give cyclic anhydrides are discussed as combination of elementary processes of organometallic reactions.
متن کاملFacile synthesis of 12-carboxamido-11-spirostenes via palladium-catalyzed carbonylation reactions.
12-Carboxamido- and 12-carboxyl-11-spirostenes were synthesized from the corresponding 12-iodo-11-ene derivative in palladium-catalyzed carbonylation reactions under mild reaction conditions. The synthesis of the iodo-alkene substrate is based on the transformation of the 12-keto derivative (hecogenin) to hydrazone, which was treated with iodine in the presence of a base (1,1,3,3-tetramethyl gu...
متن کاملChelation-assisted carbonylation reactions catalyzed by Rh and Ru complexes*
This account reviews chelation-assisted carbonylation reactions catalyzed by late transition metals. New carbonylation reactions are achieved with these catalysts in the presence of pyridin-2-ylmethanol and pyridin-2-ylmethylamine. The reactions involve activation of O−H and N−H bonds, coordination of the pyridine nitrogen to Rh being essential for the reaction to proceed. In addition, a new ty...
متن کاملEnantioselective desymmetrizing palladium catalyzed carbonylation reactions: the catalytic asymmetric synthesis of quaternary carbon center containing 1,3-dienes.
A desymmetrization protocol has been used to develop a palladium catalyzed enantioselective carbonylation process. Achiral cyclic bis-alkenyltriflates are converted to their corresponding monoester derivatives with selectivities of up to 96% ee.
