Special Issue Information

Dear Colleagues,

The continuous development of new organic synthetic methods and techniques is of great importance in medicinal chemistry and drug discovery, material sciences, agriculture sciences, etc. As a result, tremendous efforts have been made regarding both novel synthetic method development and new synthetic technique exploration. In the past several decades, a great number of novel synthetic areas have been explored, such as organocatalysis, photoredox catalysis, and electrocatalysis. Meanwhile, new synthetic techniques and instruments have also been developed, such as flow chemistry and flow reactors, microwave-assisted reactions and associated reactors, photoreactions and photoreactors, and electroreactions and electroreactors. Some of these new synthetic methods and techniques have already been utilized in industrial settings. This Special Issue aims to publish the latest research results dedicated to all aspects of new discoveries of organic synthetic methods and techniques, including, but not limited to, the discovery of new chemical transformations, catalyst development, technique development, etc.

The activation of C-H bonds is a potent tool for modifying molecular structures in chemistry. This article details the steps involved in a novel ligand bearing a bicyclic [3.3.1]-nonane framework and bissulfoxide moiety. A palladium catalyzed allylic C-H oxidation method enables a direct benzyl-allylic functionalization with the bissulfoxide ligand. Bissulfoixde ligand possesses a rapidly constructed bicyclic [3.3.1] framework and it proved to be effective for enabling both N- and C-alkylation. A total of 13 C-H activation productions were reported with good to excellent yields. This report validated that it is necessary to include bissulfoxide as a ligand for superior reactivities. Naftifine was produced utilizing developed C-H functionalization methodology in good overall yields. Full article

We describe a novel two-step approach for the synthesis of compounds with a hydroxyl-amide group (hydroxamic acids), which are widely known for their biological activity (histone deacetylase inhibitors, matrix metalloproteinases inhibitors and others). The first stage is the synthesis of N-substituted succinimide via the reaction of aromatic amine or carboxylic acid hydrazide with succinic anhydride. The second step involves the imide ring opening reaction by hydroxylamine. For both stages, universal synthetic methods are developed to exclude additional purification procedures for the target compounds. Sixteen hydroxamic acids are synthesized using the developed approach. Most of the compounds are obtained for the first time. Full article

Alkoxy radicals have been identified as versatile intermediates in synthetic chemistry in the last few decades. Over the last decade, various catalytic processes for the in situ generation of alkoxy radicals have been explored, leading to the development of new synthetic methodologies based on alkoxy radicals. In this review, we provided a comprehensive review of recent developments in the utilization of alkoxy radicals in diverse organic transformations, natural product synthesis, and the late-stage modification of bioactive molecules through the implementation of the photoredox methodology.
