Title:
ASYMMETRIC ORGANIC CATALYST
Document Type and Number:
WIPO Patent Application WO/2010/021093
Kind Code:
A1
Abstract:
Provided are a novel asymmetric organic catalyst with which it is possible to realize a high optically-active yield when said catalyst is used in a small amount, and a method for producing a compound using the same. The asymmetric organic catalyst is for addition reactions or condensation reactions and is formed from an optically active diaminocyclohexanecarboxylic acid represented by formula (1), or Brønsted acid salt thereof. (In the formula, one of R1 and R2 is a hydrogen atom and the other is an acyl group, and R3 is an alkoxy, aryloxy, aralkyloxy, amino, alkylamino, or dialkylamino group.  * is an asymmetric carbon atom, and R1HN- and R2HN- have the same configuration on the asymmetric carbon atom.)
