Cu-catalyzed cross-coupling reactions of epoxides with organoboron compounds.
A copper-catalyzed cross-coupling reaction of epoxides with arylboronates is described. This reaction is not limited to aromatic epoxides, because aliphatic epoxides are also suitable substrates. In addition, N-sulfonyl aziridines can be successfully converted into the products. This reaction provides convenient access to β-phenethyl alcohols, which are valuable synthetic intermediates.
متن کاملHeterogeneous reactions of epoxides in acidic media.
Epoxides have recently been identified as important intermediates in the gas phase oxidation of hydrocarbons, and their hydrolysis products have been observed in ambient aerosols. To evaluate the role of epoxides in the formation of secondary organic aerosols (SOA), the kinetics and mechanism of heterogeneous reactions of two model epoxides, isoprene oxide and α-pinene oxide, with sulfuric acid...
متن کاملReactions of 'K'-region epoxides of polycyclic hydrocarbons with nucleic acids and polyribonucleotides.
'K'-region epoxides have been detected as microsomal metabolites of the polycyclic hydrocarbons phenanthrene and benz[a]anthracene (Grover et al., 1971b), of pyrene and benzo[a]pyrene (Grover et al., 1972) and of 7,12-dimethylbenz[a]anthracene (Keysell et al., 1972). Synthetic 'K'-region epoxides have been found to possess biological activity as mutagens (Huberman et al., 1971; Cookson et al., ...
متن کاملAssessing the Potential for the Reactions of Epoxides with Amines on Secondary Organic Aerosol Particles.
Nuclear magnetic resonance techniques were used to study the kinetics and products of the reaction of a variety of epoxides with various amines under varying pH conditions. In agreement with a previous finding, the amine-epoxide reactions were found to be water-catalyzed and not directly dependent on the pH of the reaction environment. At pH values higher than the pK(a) of the particular amine,...
متن کاملREACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding pyridine (4) or adds as a dienophile to (lb-c).
