metal-free C≡C triple bondcleavage, dioxygen activation, and reassembly into tryptophol derivatives has been developed. This chemistry provides a novel, simple, and efficient approach to highly valuable tryptophol derivatives from simple substrates under mild conditions. The mechanistic studies may promote the discovery of new methodologies through C-C bondcleavage and dioxygen activation.

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
