Electrochemical-mediated fixation of CO<sub>2</sub>: three-component synthesis of carbamate compounds from CO<sub>2</sub>, amines and <i>N</i>-alkenylsulfonamides
An electrocatalyzed three-component cascade reaction of CO2, amines, and N-alkenylsulfonamides is developed, providing an environmentally friendly and efficient method of synthesizing a series of new carbamate compounds. This reaction meets the needs of green chemistry and promotes the participation of carbon dioxide in the three-component reaction by electro-oxidation. Pharmacological activity studies

A metal-free electrochemical intramolecular C(sp2)–Hamination using iodine as a mediator was developed. This method enables a switchable synthesis of indoline and indole derivatives, respectively, from easily available 2-vinyl anilines.
A visible‐light‐driven radical‐mediated strategy for the in situ generation of aza‐ortho‐quinonemethides from 2‐vinyl‐substituted anilines and alkyl radical precursors is described. This process enables an efficient multicomponent reaction of 2‐vinylanilines, halides, and sulfur ylides, and has a wide substrate scope and good functional group tolerance. Treatment of the cycloaddition products with
