Gold-catalyzed intermolecular Hetero-Dehydro-Diels-Alder cycloaddition of captodative dienynes with nitriles:: A new reaction and regioselective direct access to pyridines

For the first time, nitriles are used as 2 Pi electron component in a gold-catalyzed intermolecular Hetero-Dehydro-Diels-Alder cycloaddition with captodative enynes leading to the regioselective formation of pyridines.
