Amine-Catalyzed Asymmetric Cross-Aldol Reactions Using Heterofunctionalized Acetaldehydes as Nucleophiles
TL;DR: With this method, both syn- and anti-1,2-difunctionalized compounds were obtained from the same set of reactants by using the appropriate amine catalyst.
Journal ArticleDOI
Unprecedented stereochemical control in the intramolecular ene-reactions of δ,ε-unsaturated aldehydes using exceptionally bulky organoaluminum reagents: Elucidation of the transition state
TL;DR: In this paper, an unprecedented stereochemical control has been achieved in type II intramolecular ene reactions of δ,e-unsaturated aldehydes leading to trans-cyclohexanols with excellent selectivity under very mild conditions, using exceptionally bulky methylaluminum bis(4-bromo-2,6-di-tert-butylphenoxide) (MABR).
Journal ArticleDOI
Synthesis of Chiral Tritylpyrrolidine Derivatives and Their Application to Asymmetric Benzoyloxylation
TL;DR: An efficient synthesis of novel chiral tritylpyrrolidine derivatives has been developed and Representative compounds have been shown to be efficient amine organocatalysts for asymmetric benzoyloxylation.
Journal ArticleDOI
Efficient Synthesis of Cyclic Sulfoximines from N‐Propargylsulfinamides through Sulfur–Carbon Bond Formation
TL;DR: This stereospecific cyclization of N-propargylsulfinamides offers a general approach to the asymmetric synthesis of chiral cyclic sulfoximines as an emerging heterocycle in medicinal chemistry.
Journal ArticleDOI
Remote chirality control based on the organocatalytic asymmetric Mannich reaction of α-thio acetaldehydes
TL;DR: Remote chirality control leading to 1, 4-difunctionalized compounds such as 1,4-amino alcohols and 1,2-diamines was achieved by both syn- and anti-selective asymmetric Mannich reactions of α-thio acetaldehydes, the subsequent olefination and the stereospecific 2,3-sigmatropic rearrangement.
