Hsieh, Sheng-Hsiang,Gau, Han-Mou
, p. 1871 - 1874 (2006)
The first example of asymmetric alkynyl additions to aldehydes catalyzed by oxovanadium(V) catalysts of tridentate Schiff bases of β-amino alcohols 3a-h is reported. Catalytic reactions employing the best-performing catalyst 3g furnish chiral propargyl alcohols in good to excellent enantioselectivities from 73% to 99% ee. Georg Thieme Verlag Stuttgart.
Substituent effects and mechanism elucidation of enantioselective sulfoxidation catalyzed by vanadium Schiff base complexes
Zeng, Qingle,Wang, Heqing,Weng, Wen,Lin, Wenshi,Gao, Yuxing,Huang, Xiantong,Zhao, Yufen
, p. 1125 - 1127 (2007/10/03)
The effects of substituents of the Schiff base ligands on oxovanadium-catalyzed enantioselective sulfoxidation were first systematically studied, and a rational mechanism of enantioselective sulfoxidation based on our experimental data and the reported da
A highly enantioselective Strecker reaction catalyzed by titanium-N-salicyl-β-aminoalcohol complexes
Banphavichit, Vorawit,Mansawat, Woraluk,Bhanthumnavin, Worawan,Vilaivan, Tirayut
, p. 10559 - 10568 (2007/10/03)
N-salicyl-β-amino alcohols 1 were synthesized and evaluated as ligands for catalytic asymmetric Strecker reactions. N-Benzhydrylaldimines derived from aromatic and aliphatic aldehydes reacted with TMSCN in the presence of 10 mol% of Ti-1 complex to give t
