Abstract

Compounds containing a chiral oxazoline ring are one of the accessible and useful classes of ligands for asymmetric catalysis. In the recent decade, using chiral heterogeneous catalysts for the synthesis of asymmetric allylic esters by oxidation of allylic C-H bond has attracted much attention in organic chemistry. Herein chiral amino oxazoline ligands with aromatic substituent groups such as (S)-4-benzyl-4, 5 -dihydrooxazol-2-amine and (S)-4-phenyl-4, 5-dihydrooxazol-2-amine were synthesized from inexpensive and available amino acids. The obtained chiral ligands were grafted on ordered mesoporous silica SBA-15 and Characterized by TGA, DTA, BET, TEM, EDX, SEM and FT-IR. The catalytic and induced asymmetric effects of the copper (I) complexes of these new chiral heterogeneous ligands on the asymmetric allylic oxidation of cycloolefins with tert-butyl p-nitroperbenzoate as oxidant were investigated under different conditions.
