Abstract
Synthesis of organic compounds that has chirality is an important technique in the fields of pharmaceuticals, agrichemicals, health foods and the like. However, raw materials of a catalyst used for the synthesis of such compounds are expensive, and the synthesis needs many steps, so that it is difficult to reduce the cost. Linking a catalyst center to a polymer chain or a resin through an organic group enables to use the catalyst repeatedly and produce a chiral compound at low cost.
