3Chiral pyrrolidine-azole conjugates: Simple and efficient asymmetric organocatalysts for Michael addition to nitrostyrenes显示文摘Simple pyrrolidine-azole conjugates have been synthesized and found to be efficient catalysts for asymmetric Michael addition to nitrostyrenes. The identified optimal catalysts, pyrrolidine-azoles 2, 8 and 13, could catalyze the asymmetric Michael addition of a range of Michael donors and nitrostyrenes in high yields (up to 99%) and excellent stereoselectivities (up to 99:1 dr and 97% ee).ZHANG Long XU Hui MI XueLing LUO SanZhong CHENG Jin-Pei 2010Chinese Science Bulletin2010,55,17:1
4Catalytic asymmetric oxidative sulfenylation of β-ketocarbonyls using a chiral primary amine显示文摘Enantioselective oxidative construction of a C(sp^(3))–S bond has been achieved using a chiral primary amine catalyst in the presence of tert-butyl hydroperoxide and a catalytic amount of tetrabutylammonium iodide.The distinctive feature of the current reaction is coupling with nucleophilic sulfur reactants under oxidative conditions.This protocol provides facile access to chiral thioethers bearing S-containing quaternary stereocenters with good chemo-and enantiocontrol.Qi Zhang Mingying Shi Xueling Mi Sanzhong Luo 2022Organic Chemistry Frontiers2022,9,5:0
5Catalytic Asymmetric Addition and Telomerization of Butadiene with Enamine Intermediates显示文摘Herein,we report tunable asymmetric addition and telomerization of butadiene by synergistic chiral primary amine/achiral palladium catalysis.A selection of different achiral phosphine ligand in concert with the chiral primary amine-trifluoromethanesulfonic acid(TfOH)conjugates enables both chemo-and enantioselective control of the coupling with butadiene.Bidentate[(oxydi-2,1-phenylene)-bis-(diphenylphosphine)](DPEPhos)ligand led to 1,4-addition adduct whereas monodentate(p-Tol)3P ligand gave the telomerization product.A range ofα-branchedβ-ketoesters and aldehydes could be applied to afford allylation or telomerization products bearing allcarbon quaternary centers at high efficiency and good chemo-,regio-,and stereoselectivities.Yaning Wang Jie Zhang Chang You Xueling Mi Sanzhong Luo 2022CCS Chemistry2022,4,7:0
