Palladium-catalyzed tandem reaction of yne-propargylic carbonates with boronic acids: A simple method for the synthesis of fused aromatic rings through allene-mediated electrocyclization
The palladium-catalyzed tandem reactions of yne-propargylic carbonates with aryl boronic acids, 2-furyl boronic acid, and 2-thiopheneboronic acid, followed by 6π-electrocyclization to give fused ring aromatic products such as naphthalene, benzofuran, and
