Strategies for the Enantioselective Synthesis of 2-Isoxazolines and 2-Isoxazolin-5-ones Bearing Fully Substituted Stereocenters

Abstract

Although there is an abundance of methods for the enantioselective synthesis of 2-isoxazolines and 2-isoxazolin-5-ones, relatively few of these approaches have been reported when these heterocycles bear fully substituted stereocenters. In this minireview, we will detail the methods that have been used to successfully accomplish these challenging asymmetric transformations and give insights into their importance, such as allowing access to unique three-dimensional chemical space. The limitations of the currently known reactions will be discussed, as well as highlighting the future developments needed to advance the research field.
