Bio-Based Phosphate-Containing Polyester for Improvement of Fire Reaction in Wooden Particleboard.

A new phosphate-containing bio-polyester based on glycerol and citric acid was synthesized and evaluated as fire-retardant (FR) in wooden particleboards. Phosphorus pentoxide was used to first introduce phosphate esters in the glycerol followed by esterification with citric acid to produce the bio-polyester. The phosphorylated products were characterized by ATR-FTIR, H-NMR and TGA-FTIR.

Three-component assembly of amines, boronic acids, and a polyfunctionalized furanose: a concise entry to furanose-based carbohydrate templates.

A highly functionalyzed furanose derivative, accessible in five steps from D-mannose, comprising a halo-alkenyl allylic-oxirane system, undergoes a palladium catalyzed one-pot, three component, assembly with boronic acids (or alkyl boranes) and amines to give, in a complete regio- and stereocontrolled manner, a sugar based derivative with two sites of molecular diversity.
