Photocatalytic Reductive Cyclizations of Enones: Divergent Reactivity of Photogenerated Radical and Radical Anion Intermediates.
Photocatalytic reactions of enones using metal polypyridyl complexes proceed by very different reaction manifolds in the presence of either Lewis or Brønsted acid additives. Previous work from our lab demonstrated that photocatalytic [2+2] cycloadditions of enones required the presence of a Lewis acidic co-catalyst, presumably to activate the enone and stabilize the key radical anion intermedia...
متن کاملRegioselective nickel-catalyzed reductive couplings of enones and allenes.
Catalytic reductive coupling processes have been developed in numerous contexts as a strategy for the regioand stereoselective installation of alkenes. The direct coupling of a polar p system with a relatively nonpolar p system is often a successful strategy for selectively accomplishing synthetically desirable heterocouplings while avoiding undesired homocoupling of either reagent. For example...
متن کاملCatalytic regioselective oxidation of glycosides.
Discrimination among equals: A catalytic method for the selective oxidation of unprotected glycosides, both monosaccharides and disaccharides, has been developed. The resulting ketosaccharides are isolated in moderate to excellent yields. This approach provides a basis for protecting-group-free synthetic transformations of carbohydrates.
متن کاملRegioselective synthesis of vinylic derivatives of common monosccarides through their activated stannylene acetal intermediates.
The regioselective C-2-O-acrylation and metacrylation of methyl 4,6-O-benzylidene-alpha-D-glucopyranoside and methyl 4,6-O-benzylidene-alpha-D-galactopyranoside through their corresponding organotin intermediates have been studied. Regioselectivity was achieved through the formation of a tin chelate of the 2,3-diols. Thus, methyl 4,6-O-benzylidene-alpha-D-glucopyranoside and methyl 4,6-O-benzyl...
متن کاملStabilization of Free Radical Intermediates
Free radicals intermediates are formed on the surface of metal oxide semiconductors, namely Ti02 and Fe203, following the light-induced charge separation upon band-gap illu-mination. These radicals appear to adhere strongly to the ~.urfaces of the small colloidal particles (diameters between 5 and 20 nm) employed in this study. A second electron-transfer step yielding the observed end-products ...
