ChemInform Abstract: Gold(III) Chloride Catalyzed Synthesis of Chiral Substituted 3‐Formyl Furans from Carbohydrates: Application in the Synthesis of 1,5‐Dicarbonyl Derivatives and Furo[3,2‐c]pyridine.

Abstract

A series of 3‐formylfurans such as (II) and (VII) (17 examples in all), is prepared by treatment of alkynes (I) and (VI) with a gold catalyst followed by quenching with water as nucleophile.
