Recently, chiral auxiliary reagents have received great attention in asymmetric organic chemistry.
One of the most well-known ligands, oxazoline, has been widely investigated in literatures because of its chelating abilities with metals. In catalytic reactions, oxazoline (bearing bulky substituants) metal complexes can result in excellent enantioselectivity.
Therefore, we designed two novel bis-oxazoline ligands,1,4 - ((4 - phenyl-4,5 - dihydrotestosterone oxazole -2 - yl) methyl) benzene (89) and 2,2 '- (4,4', 5,5 ', 6,6' - Lioujia oxygen - [1,1 '- biphenyl] -2,2' - diyl) bis (4 - phenyl - 4 , 5 - dihydrotestosterone oxazoline) (99) and we anticipate both of them could play as good chiral ligands in the future. The synthesis of chiral oxazoline metal catalysts is still in progress in our laboratory
