Three-Component Assembly of Amines, Boronic Acids, and a Polyfunctionalized Furanose: A Concise Entry to Furanose-Based Carbohydrate Templates
摘要:
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.
