Application of directed ortho metalation reaction and electrophilic aromatic substitution allows for the regioselective synthesis of tri- and tetrasubstituted furans, thus superseding classical de novo furan construction modes.

The selectiveoxidation of 5-hydroxymethylfurfural (HMF) to produce value-added chemicals is a hot topic in the utilization of biomass, in which the development of heterogeneous catalyst and the use of O2 as terminal oxidant is desired. In this work, a series of metal ion-doped MnO2 materials are successfully prepared using liquid precipitation method, and employed as catalysts for the aerobic oxidation
