A series of cobalt complexes supported by pyridine-oxazoline (Pyox) and quinoline-oxazoline (Quox) were synthesized. Determined by single crystal X-ray crystallography, complexes 6a and 7c adopted distorted octahedron and trigonal bipyramid geometries, re

The Pd-catalyzed asymmetric aza-Wacker-type cyclization reaction of the olefinic tosylamides with molecular oxygen as the green oxidant was developed. Under the optimized conditions, excellent catalytic activity and good enantioselectivity with up to 74%
Palladium(II)-catalyzed enantioselective aerobic dialkoxylation of 2-propenyl phenols: A pronounced effect of copper additives on enantioselectivity

A direct O2-coupled Pd(II)-catalyzed enantioselective dialkoxylation of 2-propenylphenols has been developed by utilizing chiral quinoline oxazoline ligands. A detrimental effect of added copper salts on enantioselectivity was observed which is attributed to the displacement of the chiral ligand off of Pd(II). Copyright
Steric effects of the ligand in the enantioselective palladium-catalyzed allylic alkylation using chiral oxazolinylpyridines

, p. 543 - 550 (2007/10/03)
Eight new chiral oxazolinylpyridines were prepared and assessed in the enantioselective palladium-catalyzed allylic substitution of 1,3- diphenylprop-2-enyl acetate with dimethyl malonate. Catalytic activity and enantioselectivity were found to be highly
Palladium-catalyzed allylic alkylation using pyridino-oxazolines and quinolino-oxazolines as ligands - Influence of steric factors

, p. 3437 - 3443 (2007/10/03)
Four new chiral pyridino- and quinolino-oxazolines were subjected to the palladium-catalyzed alkylation of 1,3-diphenyl-2-propenyl acetate. The enantioselectivity varied (82-88% ee) with the steric properties of the ligands. The results are discussed in connection with results previously obtained using analogous ligands.
