Gold(i)-catalyzed cyclization of 2-(1-alkynyl)-alk-2-en-1-one oximes: a facile access to highly substituted N-alkoxypyrroles.

A gold(i)-catalyzed cyclization of 2-(1-alkynyl)-alk-2-en-1-one oximes with numerous nucleophiles has been developed. This strategy provides a relatively safe, mild, simple access to a mass of highly substituted N-alkoxypyrroles.
