Efficient generation and increased reactivity in cationic gold via Bronsted acid or lewis acid assisted activation of an imidogold precatalyst

Bronsted or Lewis acid assisted activation of an imidogold precatalyst (L-Au-Pht, Pht = phthalimide) offers a superior way to generate cationic gold compared with the commonly used silver-based system. It is also broadly applicable for most common gold-catalyzed reactions. For reactions that require milder conditions, milder acids can be used for optimized efficiency.

Bronsted acid-promoted intramolecular carbocyclization of alkynals leading to cyclic enones

TFA-promoted exo carbocyclizations of nonterminal 7-alkynals gave good to excellent yields of seven-membered cycloalkenones, a medium-sized functionalized ring present in natural products with relevant pharmacological properties. Nonterminal 5-and 6-alkyn
