    • The present invention relates to a 5,5′-position linked 1,1′-biphenyl axis chiral ligand in chemical industry field. The present invention incorporates both the central chirality of oxazoline and the axial chirality of diphenyls. Such ligand can be used in various asymmetric reactions catalyzed by metal with high reactivity and stereoselectivity, and thus represents a good application outlook.The ligand of the present invention has the formula of: wherein: n=5, 6, 7, 8, 9, 10, 11 or 12; R1=hydrogen, alkyl, substituted or unsubstituted aryl, substituted or unsubstituted benzyl; R2=hydrogen, alkyl, substituted or unsubstituted aryl, substituted or unsubstituted benzyl; R3=hydrogen, alkyl, substituted or unsubstituted aryl, substituted or unsubstituted benzyl; R4=hydrogen, alkyl, substituted or unsubstituted aryl, substituted or unsubstituted benzyl.
    • 本发明涉及化学工业领域中5,5'-位连接的1,1'-联苯轴线手性配体。 本发明既包括恶唑啉的中心手性和二苯基的轴向手性。 这种配体可用于具有高反应性和立体选择性的金属催化的各种不对称反应中,因此代表了良好的应用前景。 本发明的配体具有下式:其中:n = 5,6,7,8,9,10,11或12; R1 =氢,烷基,取代或未取代的芳基,取代或未取代的苄基; R2 =氢,烷基,取代或未取代的芳基,取代或未取代的苄基; R3 =氢,烷基,取代或未取代的芳基,取代或未取代的苄基; R4 =氢,烷基,取代或未取代的芳基,取代或未取代的苄基。
