Chiral dirhodium(II) carboxamidates catalyze highly stereoselective hetero-Diels-Alder
reactions of aromatic aldehydes with methyl-substituted Danishefsky’s dienes with
high turnover numbers. The methyl substituents of the diene influence both enantioselectivity
in product formation and the rate of the reaction in the presence of chiral dirhodium(II)
Lewis acids.
hetero-Diels-Alder reaction - catalytic asymmetric synthesis - chiral Lewis acids
- dirhodium(II) carboxamidates - cycloaddition
