Construction of tetrahydrofurans by PdII/PdIV-catalyzed aminooxygenation of alkenes.
Catalytic transformations involving Pd s-alkyl or s-aryl intermediates are widely used in organic synthesis and offer attractive routes to many valuable products. However, the vast majority of these reactions proceed by Pd/Pd mechanisms. As a result, the diversity of structures/bonds that can be constructed is constrained by the limitations of this redox cycle. Recent studies have explored the ...
متن کاملPlatinum-catalysed aerobic 1,2-aminooxygenation of alkenes.
Platinum(II) salts in combination with copper salts and molecular oxygen catalyse an unprecedented intramolecular transfer of heteroatoms to alkenes to yield aminooxygenation products under sustainable conditions.
متن کاملOrganocatalytic synthesis of polysubstituted tetrahydrofurans from alkenes†
A novel, organocatalytic and environmentally friendly protocol for the synthesis of polysubstituted tetrahydrofurans from trivial starting materials has been described. By employing 2,2,2-trifluoroacetophenone-mediated oxidation, which utilizes H2O2 as a green oxidant, we introduce a sustainable procedure that embraces the principles of green chemistry for the production of substituted tetrahyd...
متن کاملDiastereoselective aminooxygenation and diamination of alkenes with amidines by hypervalent iodine(III) reagents.
Diastereoselective anti-aminooxygenation and anti-diamination of alkenes with amidines were enabled by hypervalent iodine(III) reagents such as PhI(OCOR)2 and PhI(NMs2)2, respectively. The present transformation offers diastereochemically pure dihydroimidazoles divergently from E- and Z-alkenes.
