5-Hydroxymethyl-2-furfural (5-HMF) is a platform molecule with a rich and versatile chemistry, which represents a promising biobased molecule for the formation of biopolymers with potential for a ...

Cycloaddition of 1,3-dipoles to allenes usually proceeds in a nonselective way. Herein, we report on an efficient metal-free cycloaddition of nitrile oxides to readily available ...
