A gold‐catalyzed desilylative cyclization was developed for facile synthesis of bridged tetracyclic indolenines, a common motif in many natural indole alkaloids. An antimicrobial screen of the cyclization products identified one compound which selectively potentiates β‐lactam antibiotics in methicillin‐resistant S. aureus (MRSA), and re‐sensitizes a variety of MRSA strains to β‐lactams.
