Naphthyl-substituted Bisoxazoline-Copper(Ⅰ) Catalysts[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2012,51(4):61-67.DOI:
Synthesis of naphthyl substituted malonyl-derived (Box) and pyridine-based bisoxazolines (PyBox) as well as their applications in the asymmetric allylic oxidation of cyclohexene with
t-
butyl
p-
nitroperbenzoate have been carried out
with significantly improved reactivity (75%) while maintaining very good enantioselectivity (85%) using the ligand with 1-naphthyl group as the side chain on oxazoline ring.The correlations between the nature of the substituents on the bisoxazolines and the reactivity/selectivity have been established.
