Highly enantioselective nitroaldol reaction catalyzed by new chiral copper complexes.
Remarkable generality in scope of DATs/Cu catalysts for enantioselective nitroaldol reaction is described; excellent levels of stereoinduction are recorded for a range of aldehydes (ee 81-99%, 17 examples) and the possibility to employ the present catalytic system as the key step for the preparation of highly functionalized tetrahydro-isoquinolines is demonstrated.
متن کاملEnantioselective Release Behavior of Ketoprofen Enantiomers from Alginate-metal Complexes, Monitored by Chiral HPLC
Alginate-metal complexes were prepared with divalent (Ca, Ba, Zn) and trivalent metals (Fe, Al) via congealing method in form of beads. Alginate mixed metals (Ca & Fe) complexes were also prepared by simultaneous and consecutive congealing. The studied beads were blank beads and racemic ketoprofen (KTP) loaded beads. Metal content was determined by atomic absorption spectroscopy and was 1.8% to...
متن کاملCatalytic amide allylation of α-ketoesters: extremely high enantioselective synthesis of ester functionalised α-methylene-γ-butyrolactones.
This communication reports a significant breakthrough on the novel catalytic amide allylation to the acyclic α-ketoester systems, achieving satisfactorily high yields and extremely high levels of the asymmetric induction to allow for highly enantioselective synthesis of ester functionalised α-methylene-γ-butyrolactones.
متن کاملCatalytic enantioselective Conia-ene reaction.
An enantioselective intramolecular Conia-ene reaction of beta-dicarbonyl compounds and alkynes to afford methylene cyclopentanes is described. The reaction employs a DTBMSegphos-Pd(II)/Yb(III) dual catalyst system that allows for the asymmetric synthesis of all-carbon quaternary centers and generates a product containing an alkene that can be further manipulated.
