Title:
希土類アルコキシドの触媒活性評価法
Document Type and Number:
Japanese Patent JP4140756
Kind Code:
B2
Abstract:
This invention provides a method of evaluating the catalytic activity of a rare earth alkoxide used as a starting material of a basic catalyst or an asymmetric synthesis catalyst. The rare earth alkoxide used as the subject of evaluation and 2,2'-dihydroxy-1, 1'-binaphthol are used as the starting material to prepare a rare earth complex catalyst which is then used to conduct the asymmetric epoxidation of an enone. The epoxy enone formed by this reaction, the unreacted enone, and the enantiomeric excess are measured, and from these results, the catalytic activity of the rare earth alkoxide is evaluated.
