Aminofluorination-Based Structural Modification of Curcumol for the Construction of 3D-Shaped Natural Product Fragment Library

Abstract

The biological significance of sp 3 -rich synthetic scaffolds with natural product like features yet distinct global frameworks is being increasingly recognized in medicinal chemistry and biochemistry. Herein, a fragment library consisting of 3D-shaped natural product fragments was assembled. Library construction was performed by photocatalytic amidofluorination of curcumol to incorporate amine and fluorine as potential binding groups and synthetic growth points. Through this strategy, a fragment library of 24 fragments was generated, which was demonstrate to have high three-dimensionality, natural product likeness and superior fragment-like properties, covering a novel chemical space in fragment based drug discovery.
