One-step Synthesis of Cyanated Pyrazolo[1, 5-a]pyridines Utilizing N-Aminopyridines as 1,3-Dipole and Nitrogen Source
Organic chemistry frontiers(2023)
摘要
By utilizing the dual reactivity function of N -aminopyridinium ylides, we developed a direct [3 + 2]-cycloaddition of N -aminopyridinium ylides and ynals to build the pyrazolo[1,5- a ]pyridine core while introducing a cyano group.
