Dual reactivity of imidic carbonyl ylides in Rh(II)-catalyzed reactions of α-diazocarbonyl compounds with succinimide
نویسندگان
چکیده
Stabilization of imidic carbonyl ylides derived from alpha-diazocarbonyl compounds and succinimide occurs in two different ways: ylides from diazoesters experience a [1,4]-hydrogen shift to produce the corresponding O-alkylimidates while their analogues with at least one acyl group undergo [1,5]electrocyclization yielding 1,3-dioxoles.

Catalytic decomposition of diazoacetylacetone, diazoacetoacetic, diazomalonic, and diazoacetic esters using dirhodium tetraacetate in the presence of isothiazol-3(2H)-one 1,1-dioxides and a number of N-(arenesulfonyl)carboxamides in solutions of methylene chloride or dichloroethane gives rise to O-alkylation of the imidic carbonyl groups by Rh(II)-carbenoids and the formation of O-alkylimidates...

Rh(II)-сatalyzed reactions of aroyldiazomethanes, diazoketoesters and diazodiketones with α,β-unsaturated δ-aminoesters, in contrast to reactions of diazomalonates and other diazoesters, give rise to the Wolff rearrangement and/or oxidative cleavage of the initially formed N-H-insertion products. These oxidation processes are mediated by Rh(II) catalysts possessing perfluorinated ligands. The f...

Introduction Since their discovery in the late 1960s, the [2,3]-sigmatropic rearrangements of sulfonium ylides have received considerable attention because of their applications in organic synthesis and their probable involvement in biochemical processes. The most common method for sulfonium ylide generation involves the removal of a proton from a sulfonium salt with a strong base. However, a m...

Carbonyl ylides are generally non-isolable reactive intermediates and have been extensively utilized as the dipole in 1,3-dipolar cycloaddition reactions with electron-deficient and electron-rich dipolarophiles to afford polycyclic compounds including five-membered oxacycles. The most efficient method for generating the carbonyl ylide is the interaction of a metal carbene complex with the oxyge...
