Asymmetric Hetero Diels-Alder Reaction Catalyzed by Chiral Ytterbium(III) Phosphate {Yb[(R)-(-)-BNP]3}: Remarkable Ligand Effect on the Enantioselectivity

2,6-Lutidine was found to be an effective additive for the chiral ytterbium(III) phosphate {Yb[(R)-(-)-BNP]3}-catalyzed asymmetric hetero Diels-Alder reaction thus achieving high enantioselectivity (up to 93% ee) at room temperature.

Highly efficient enantioselective synthesis of optically active dihydropyrones by chiral titanium (iv) (5,5',6,6',7,7',8,8'-octahydro-1,1'-bi-2-naphthol) complexes

The asymmetric hetero-Diels-Alder reaction of Danishefsky's diene and an aldehyde catalyzed by 20 mol% chiral H8-BINOL-Ti(IV) affords the corresponding 2-substitutent-2,3-dihydro-4H-pyran-4-one with ees of up to 99% under mild reaction conditio

Asymmetric hetero Diels-Alder reaction catalyzed by chromium complexes of heterogeneously hybridized salen/salan ligands

Various heterogeneously or homogeneously hybridized salen/salan ligands were synthesized, and study of hetero Diels-Alder reactions using their chromium complexes as catalysts revealed that a well-designed heterogeneously hybridized ligand serves as a chi

Methods of performing cycloadditions, reaction mixtures, and methods of performing asymmetric catalytic reactions

Methods of performing cycloadditions are described that include (a) combining a first reactant and a second reactant in a hydrogen bonding solvent to form a reaction mixture; and (b) reacting the first reactant and the second reactant to form a cycloadduc
