Chiral chelating agents and chiral catalysts, which are formed from the chiral chelating agents and metal, are described. One chiral chelating agent has a general formula (1) as illustrated below:
1
wherein R represents H, methyl, ethyl, a primary, secondary or tertiary straight, branched or cyclic alkyl group having 3-7 carbon atoms, a heterocyclic or aromatic group, an aromatic group substituted at the 2-, 3- or 4-position, an aromatic-like group, or a naphthyl or naphthyl-derived group, and n is an integer between 0 and 4.
手性螯合剂和手性催化剂是由手性螯合剂和金属形成的。其中一种手性螯合剂具有如下所示的一般式(1):
1
其中R代表H、甲基、乙基、具有3-7个碳原子的一级、二级或三级直链、支链或环烷基基团、杂环或芳香基团、在2-、3-或4-位取代的芳香基团、类芳香基团,或者萘基或萘基衍生基团,n为0到4之间的整数。
