The main purpose of this review article is to present selected asymmetric synthesis reactions in which chemical and stereochemical outcomes are dependent on the use of an appropriate chiral catalyst. Optically pure or enantiomerically enriched products of such transformations may find further applications in various fields. Among an extremely wide variety of asymmetric reactions catalyzed by chiral systems, we are interested in: asymmetric cyclopropanation, Friedel–Crafts reaction, Mannich and Michael reaction, and other stereoselective processes conducted in the presence of zinc ions. This paper describes the achievements of the above-mentioned asymmetric transformations in the last three years. The choice of reactions is related to the research that has been carried out in our laboratory for many years.

手性催化剂促进的选择性不对称反应的最新进展：环丙烷化、弗里德尔-克拉夫茨、曼尼希、迈克尔和其他锌介导的过程——更新

这篇评论文章的主要目的是介绍选定的不对称合成反应，其中化学和立体化学结果取决于使用适当的手性催化剂。这种转化的光学纯或对映异构体富集的产物可以在各个领域找到进一步的应用。在手性体系催化的各种不对称反应中，我们感兴趣的是：不对称环丙烷化、弗里德尔-克拉夫茨反应、曼尼希和迈克尔反应，以及在锌离子存在下进行的其他立体选择性过程。本文介绍了上述非对称变换近三年取得的成果。反应的选择与我们实验室多年来进行的研究有关。
