Controlled gold-catalyzed 5- exo-dig cyclization of 3-sulfur-substituted 1,3-dien-5-ynes for synthesizing fulvenes and the in situ reaction with indoles

Year: 2025

Type: article

Abstract: Sulfur-substituted fulvenes have been synthesized from 1,3-dien-5-ynes via a gold-catalyzed 5- exo-dig cyclization. Activation by the gold and Brønsted acid catalysts generates fulvenium ions, enabling one-pot reaction with indoles.
