The invention relates to an optically active ionic liquid containing (a) a cationic species having a heterocyclic ring; and (b) an anionic species. This cationic species contains at least one asymmetric carbon atom. This ionic liquid can be produced by a process including the step of reacting a heterocyclic compound, which contains an asymmetric carbon atom, with an alkylation agent. The ionic liquid can be useful as a solvent for asymmetric syntheses.
本发明涉及一种光学活性离子液体,其中含有 (a) 具有杂环的阳离子种类;和 (b) 阴离子种类。该阳离子种类至少含有一个不对称碳原子。这种离子液体可以通过包括使含有一个不对称碳原子的杂环化合物与烷基化剂反应的步骤的工艺制得。这种离子液体可用作不对称合成的溶剂。
