A gold-catalyzed acid-assisted regioselective cyclization for the synthesis of polysubstituted oxazoles

Polysubstituted oxazole derivatives are obtained through a regioselective gold-catalyzed reaction of α-alkynylamides and alkynoates in the presence of nitriles. The intermediary obtained gold carbenes are generated by alkyne oxidation with a pyridine N-oxide. Acidic conditions ensure that only one o...

Description
Summary:Polysubstituted oxazole derivatives are obtained through a regioselective gold-catalyzed reaction of α-alkynylamides and alkynoates in the presence of nitriles. The intermediary obtained gold carbenes are generated by alkyne oxidation with a pyridine N-oxide. Acidic conditions ensure that only one of the two carbonyl oxygen atoms in these intermediates selectively cyclizes to the products in excellent yields.
