A substituted paracyclophane is described of formula (I) wherein Xl and X2 are linking groups comprising between 2 to 4 carbon atoms, Y1 and Y2 are selected from the group consisting of hydrogen, halide, oxygen, nitrogen, alkyl, cycloalkyl , aryl or heteroaryl, Z1, Z2 and Z3 are substituting groups that optionally contain functional groups, a, b, c, d, e and f are 0 or l and a + b + c + d + e + f = 1 to 6. PreferablyX1 and X2 are -(C2H4)- and a + b + c + d + e + f = 1 or 2. The substituted paracyclophane provides transition metal catalysts that demonstrate high activity and selectivity for asymmetric reactions.
描述了一种具有以下式(I)的取代对环戊烷,其中X1和X2是包含2到4个碳原子的连接基团,Y1和Y2选自氢、卤素、氧、氮、烷基、环烷基、芳基或杂环芳基,Z1、Z2和Z3是可选地含有官能团的取代基团,a、b、c、d、e和f为0或1,且a + b + c + d + e + f = 1到6。最好X1和X2为-(C2H4)-,且a + b + c + d + e + f = 1或2。这种取代对环戊烷提供了过渡金属催化剂,表现出对不对称反应具有高活性和选择性。
