Asymmetric propionate aldol reactions of a chiral lithium enolate accessible from direct enolization with n-butyllithium
(ARKAT USA, Inc., 2005)
Artículo / Artikulua,
The presented lithium enolate-based methodology is suitable for access to propionate syn-aldol
motifs with high levels of stereocontrol. The reactive lithium enolate species is generated by
direct treatment of a camphor-based ...
Asymmetric assembly of all‐carbon tertiary/quaternary nonadjacent stereocenters through organocatalytic conjugate addition of α‐cyanoacetates to a methacrylate equivalent
(Wiley, 2016)
Artículo / Artikulua,
An efficient, highly diastereo- and enantioselective assembly of acyclic carbonyl fragments possessing nonadjacent all-carbon tertiary/quaternary stereoarrays is reported based on a Brønsted base catalyzed Michael ...
α-Hydroxy ketones as masked ester donors in Brønsted base catalyzed conjugate additions to nitroalkenes
(Wiley, 2018)
Artículo / Artikulua,
The catalyst-controlled enantioselective direct addition reaction of enolizable esters and related carboxylic
acid derivatives to p electrophiles remains a difficult synthetic transformation. In this study, the suitability ...
