Synthesis of Substituted Pyridines from Cascade [1 + 5] Cycloaddition of Isonitriles to

Jieping Zhu

A novel strategy for de novo synthesis of pyridines featuring an unprecedented a-addition of aldehyde and enamide to isonitrile as a key step is described. Under mild conditions, a cascade reaction involving Zn(OTf)(2)-promoted [1 + 5] cycloaddition of iso ...
