Enantioselective allylation of aldehydes catalyzed by chiral indium(III) complexes immobilized in ionic liquids.
In the presence of chiral catalytic complexes prepared from In(OTf)3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylic alcohols in high enantioselectivities (86-94% ee) and good yields (68-89%); the chiral catalysts immobilized in ionic liquids could be reused with comparable enantioselectivities and yields.
متن کاملAntibody-Catalyzed Enantioselective Robinson Annulation
We report an antibody that is remarkable in that it catalyzes both steps of an important synthetic transformation, the Robinson annulation. The Robinson annulation which accomplishes, in net terms, the conversion of a f c occupies a key role in organic synthesis.1 In most instances, the overall annulation is comprised of an alkylation (or Michael addition) step leading to b followed by a cyclod...
متن کاملPalladium-Catalyzed, Enantioselective Heine Reaction
Aziridines are important synthetic intermediates for the generation of nitrogen-containing molecules. N-Acylaziridines undergo rearrangement by ring expansion to produce oxazolines, a process known as the Heine reaction. The first catalytic, enantioselective Heine reaction is reported for meso-N-acylaziridines where a palladium(II)-diphosphine complex is employed. The highly enantioenriched oxa...
متن کاملEnantioselective transition metal-catalyzed allylic
tions have been developed as fundamentally important crosscoupling reactions. In general, the heteroatom nucleophiles in these reactions have been largely limited to alkylamines, anilines, carboxylates and phenols. Our laboratory is interested in searching the synthetically useful heteroatom nucleophiles for the synthesis of functionalized allylic compounds (Fig. 1). As our successful examples,...
متن کاملGold(I)-catalyzed enantioselective polycyclization reactions.
A series of enantioselective polycyclization reactions, catalyzed by a cationic bisphosphine gold complexes, are described. The polycyclization reactions, which employ an alkyne as an initiating group, begin with a gold-promoted 6-exo-dig cyclization and can be terminated with a variety of nucleophiles including carboxylic acids, phenols, sulfonamides, and electron-rich aryl groups. This method...
