Asymmetric synthesis method using a chiral Bronsted acids as catalyst

摘要

Providing a usable compounds as catalysts for asymmetric synthesis that can be and easily synthesized without using a metal such as lanthanide series element, and the asymmetric synthesis method provides an asymmetric synthesis method using this compound and it is to provide a chiral compound obtained by. The present invention is intended to use a chiral Bronsted acids as catalysts in asymmetric synthesis, as the chiral Bronsted acids are those represented by the following general formula (1) or the following general formula (3). Furthermore, the present invention is to provide an asymmetric synthesis method using the catalyst, is to provide a chiral compound obtained from asymmetric synthesis using the catalyst.
