An I2-promoted formal [3+2] cycloaddition for access to oxazoles has been demonstrated. This is the first example of a Lewis acid-promoted formal [3+2] cycloaddition of isocyanides with methyl ketones involves...

A silver‐induced cycloaddition of isocyanides with acyl chlorides has been developed. This transition metal‐catalyzed strategy provides an effective and scalable approach for the formation of 2,5‐disubstituted oxazoles in good to high yields. The employed silver‐based MOF catalyst can be efficiently recycled without compromising the yield.
The invention provides antimicrobial agents and methods of using the agents for sterilization, sanitation, antisepsis, disinfection, and treatment of infections in mammals.
