Reactions of vinyl ethers with cobalamins and cobaloximes.
Sir: We recently reported 1 that cobaloximes and cobalamins reacted with vinyl ethers, in the presence of alcohols, to give aceta Is containing cobalt-carbon cr-bonds. On the basis of these, and earlier 2 experiments, we suggested that the reactions proceeded via the intermediary of a Co(lII)-olefin 7r-complex. Schrauzer, et al.,3 then reported that they were unable to confirm our results and c...
متن کاملTriphenylphosphine mediated synthesis of functionalized aryl-vinyl ethers from7-hydroxy coumarin and methyl acetylene carboxylate
7-hydroxy coumarin undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine, and bysubstituation the corresponding aryl vinyl ethers was obtained in good yields
متن کاملSynthesis of Functionalized Aryl-vinyl Ethers as Building Blocks and Auxiliaries in Organic Synthesis
5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.
متن کاملPd-catalyzed addition of boronic acids to ynol ethers: a highly regio- and stereoselective synthesis of trisubstituted vinyl ethers.
A Pd-catalyzed addition of boronic acids to ynol ethers has been realized, delivering trisubstituted vinyl ethers in good yields with perfect control of the regio- and stereoselectivity. The reaction proceeds under mild conditions and exhibits excellent functional group compatibility. Moreover, the resultant products can be converted into pentasubstituted benzenes via the tandem Diels-Alder/aro...
متن کاملFormation of enamides via palladium(II)-catalyzed vinyl transfer from vinyl ethers to nitrogen nucleophiles.
Palladium(II) complexes catalyze the formation of enamides via the formal cross-coupling reaction between nitrogen nucleophiles and vinyl ethers. These vinyl transfer reactions proceed in good yields with amide, carbamate, and sulfonamide nucleophiles, and the optimal catalyst is (DPP)Pd(OCOCF(3))(2) (DPP = 4,7-diphenyl-1,10-phenanthroline).
