Journal ArticleDOI
How to make five contiguous stereocenters in one reaction: asymmetric organocatalytic synthesis of pentasubstituted cyclohexanes.
Journal ArticleDOI
Catalytic enantioselective inverse-electron demand 1,3-dipolar cycloaddition reactions of nitrones with alkenes
TL;DR: In this article, a general reaction protocol for catalytic enanti-lective 1,3-dipolar cycloaddition reaction of nitrones, activated by chiral Lewis acids, with electron-rich alkenes has been developed.
Journal ArticleDOI
On the Intermediates in Chiral Bis(oxazoline)copper(II)‐Catalyzed Enantioselective Reactions—Experimental and Theoretical Investigations
TL;DR: It is shown that the absolute configuration of the hetero-Diels-Alder adduct obtained from the reaction of ethyl glyoxylate with 1,3-cyclohexadiene in the presence of the chiral bis(phenyloxazoline)copper(II) is dependent on the solvent, while the enantiomeric excess for the adduct is independent of the solvent.
Journal ArticleDOI
Catalytic Asymmetric Hetero-Diels−Alder Reactions of Ketones: Chemzymatic Reactions
TL;DR: In this article, a general catalytic hetero-Diels−Alder reaction for ketones has been developed, and for the first time a general reaction protocol is disclosed where the selectivity and activity of a chiral Lewis...
Journal ArticleDOI
Catalytic Enantioselective Aza Diels–Alder Reactions of Imino Dienophiles
TL;DR: The hetero Diels-Alder reaction of α-imino esters 1 with activated conjugated dienes 2 (R=H, Me) needs only 1 mol% of a 2,2'-bis(diarylphosphanyl)-1,1'-binaphthyl (BINAP) copper(I) complex as the catalyst to generate the adducts in good yields and with enantioselectivities up to 96%.
