Journal ArticleDOI
Design of Brønsted Acid-Assisted Chiral Lewis Acid (BLA) Catalysts for Highly Enantioselective Diels−Alder Reactions
TL;DR: In particular, excellent enantioselectivity was achieved due to intramolecular hydrogen bonding interaction and attractive π−π donor−acceptor interaction in the transition-state assembly by hydroxy aromatic groups in a chiral BLA catalyst as mentioned in this paper.
Journal ArticleDOI
Chiral(acyloxy)borane (CAB): a powerful and practical catalyst for asymmetric Diels―Alder reactions
Journal ArticleDOI
Methylaluminum bis(2,6-di-tert-butyl-4-alkylphenoxide). A new reagent for obtaining unusual equatorial and anti-cram selectivity in carbonyl alkylation
Journal ArticleDOI
O-nitroso aldol synthesis: Catalytic enantioselective route to α-aminooxy carbonyl compounds via enamine intermediate
TL;DR: After survey of pyrrolidine-based Brønsted acid catalyst, tetrazole catalyst (3f) was found to be optimal in synthesis of aminooxy carbonyl compounds in high yields, with complete enantioselectivity not only for aldehydes but also for ketones.
Journal ArticleDOI
Chiral allenylboronic esters as practical reagents for enantioselective carbon-carbon bond formation. Facile synthesis of (-)-ipsenol.
TL;DR: A stereospecific synthetic route to (-)-ipsenol is described, a new asymmetric synthetic reaction using chiral allenyl boronic esters using allylic nucleophiles to carbonyl compounds, and much discussion on diastereoselectivity.
