Organoyttrium-Catalyzed Sequential Cyclization/Silylation Reactions of Nitrogen-Heteroaromatic Dienes Demonstrating “Aryl-Directed” Regioselectivity

The reaction of 1-allyl-2-vinyl-1H-pyrroles and 1-allyl-2-vinyl-1H-indoles with arylsilanes in the presence of catalytic [CpTMS 2Y(μ-Me)]2 leads to highly selective cyclization/silylation events. In this process the active catalyst for the reaction, “CpTMS 2YH”, undergoes initial olefin insertion at...
