Two‐Step Preparation of Diverse 3‐Amidofurans from Chitin

Abstract The synthesis of 3‐amidofurans is laborious due to the difficulty installing a nitrogen substituent at the C3 position of the furan heterocycle. 3‐Acetamido‐5‐acetylfuran (3A5AF), readily available from chitin, is a versatile biorenewable platform that can be converted into a range of functionally rich 3‐amidofurans, streamlining access to this underexplored heteroaromatic chemical space.
