摘要:The present invention discloses a targeted synthesis method for the synthesis of asymmetric monoesters and/or symmetrical diesters of citric acid through acidic esterification by using boric acid or a boronic acid as a catalyst. The boric/boronic acid simultaneously acts as a catalyst, as well as a 'protecting group' for the tertiary carboxylic acid, and therefore specifically only the asymmetric monoesters or symmetrical diesters are created.

标 题 :Chiral broensted acid catalyst for asymmetric synthesis and method of asymmetric synthesis with the catalyst
发明人：AKIYAMA TAKAHIKO
权利人:TOAGOSEI CO LTD
摘要:A compound usable as an asymmetric synthesis catalyst which can be easily synthesized without using any metal such as a lanthanoid group element; a method of asymmetric synthesis with the compound; and a chiral compound obtained by the asymmetric synthesis method. A Broensted acid is used as a catalyst in asymmetric synthesis, the chiral Broensted acid being represented by formula (1) below or formula (3) below. The asymmetric synthesis method employs the catalyst. Asymmetric synthesis with the catalyst gives a chiral compound.
