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 کاملSite specific labelling of sugar residues in oligoribonucleotides: reactions of aliphatic isocyanates with 2' amino groups.
Considerable effort has been directed towards studying the structure and function of nucleic acids and several approaches rely on the attachment of reporter groups or reactive functional groups to nucleic acids. We report here the selective modification of 2-amino groups in oligoribonucleotides, through their reaction with aliphatic isocyanates, to give the corresponding 2'-urea derivatives in ...
متن کاملTandem addition-cyclization reactions of 2-alkynylbenzenamines with isocyanates catalyzed by PdCl2.
Tandem addition-cyclization reactions of 2-alkynylbenzenamines with isocyanates catalyzed by palladium chloride are described. This reaction is performed in the presence of 10 mol% of palladium chloride in THF at 80 degrees C, which provides an efficient and practical route for the synthesis of 1,2-disubstituted indoles.
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., ...
