Abstract

The ring-closing metathesis transformation has been employed to construct a library of functionalized 2-pyridones and pyridine triflates. Using this mild approach, a range of substituent patterns can be built into the aromatic core, including groups which can be demanding to incorporate using alternative protocols.

Key words

ring-closing metathesis - elimination - 2-pyridone - pyridine - triflation
