Unusual Approach to 3-Aryl-2-aminopyridines through a Radical Mechanism: Synthesis and Theoretical Rationale from Quantum Mechanical Calculations
摘要:
Tris(trimethylsilyl)silane and azobis(cyclohexanenitrile) promoted the easy intramolecular arylation of aryl bromopyridine carbamates through a radical [1,6] ipso substitution process. These substrates showed a preference for this type of reaction over the alternative [1,7] addition. The results were rationalized by making use of quantum mechanical calculations and computer graphics.
