外在力场对异佛尔酮不对称氧化反应的影响*

本文通过紫外、红外和圆二色（CD）光谱表征考察了外在离心力场对非手性化合物异佛尔酮不对称氧化生成光学活性产物的影响。结果表明离心力场能够诱导产物的对映体过量，在顺时针和逆时针旋转力场中得到的产物CD230信号相反并随转速的增大而增大。作者推测，顺时针和逆时针圆周离心运动（轴矢量）结合地球在时空上的天然线性运动（极矢量）形成的左、右手螺旋运动的不对称作用可能是诱导反应对映体过量的力学原因。

Effect of external force field on asymmetric oxidation reaction of isophorone*

In this paper, asymmetric synthesis of oxidation reaction of achiral isophorone influenced by artificial centrifugal force field was studied. The reaction system was characterized by UV, Infrared (IR) and Circular dichroism (CD). The CD_ 230 of product mixture was positive and negative in the clockwise and anticlockwise rotation, respectively, and the effect was dependent on the rotation speed. The data indicated that enantiomeric excess of isophorone oxide was able to be caused by the external centrifugal force field. It was suggested that the chiral effect was resulted from the chiral interaction between the chiral right- and left- handed helical motion and the chiral enantiomers.
