Base mediated synthesis of functionalized 2‐(alkynyl)arylnitriles and their molecular docking study with aromatase receptor

A simple, efficient, and transition metal-free approach to synthesize functionalized 2‐(alkynyl)benzonitriles has been developed using suitably functionalized 2H-pyran-2-ones and 4-phenyl/trimethylsilanyl-but-3-yn-2-ones as precursors. The reaction proceeds in presence of a base at room temperature to yield internal as well as terminal alkynes. The structure of the synthesized compound was confirmed by single-crystal X-ray also. The molecular docking study was made to evaluate the binding mode of action of newly synthesized alkyne derivatives with known human breast cancer target receptor aromatase (PDB ID: 3EQM).
