Gold-catalyzed [4+1]-annulation reactions between anthranils and 4-methoxy-1,2-dienyl-5-ynes involving a 1,2-allene shift

Gold-catalyzed [4+1]-annulations of 4-methoxy-1,2-dienyl-5-ynes with anthranils are described. The mechanism of these annulations involves nitrene formation of α-imino gold carbenes that undergo a 1,2-allene shift to form (pyrrol-2-yl) methylgold intermediates. With allenyl ester substrates, these gold intermediates become enolate species to enable intramolecular aldol reactions to form useful pyrrolo[1,2-a]quinoline derivatives.

Gold-Catalyzed [4 + 1]-Annulation Reactions between 1,4-Diyn-3-ols and Isoxazoles to Construct a Pyrrole Core

This work reports gold-catalyzed [4 + 1]-annulation reactions between 1,4-diyn-3-ols and isoxazoles or benzisoxazoles to yield pyrrole derivatives. The reaction chemoselectivity is controlled by an initial attack of an isoxazole at a less hindered alkyne to form gold carbenes, further inducing a 1,2-migration of a second alkyne group. A broad substrate scope of 1,4-diyn-3-ols, isoxazoles and even benzisoxazoles highlighted the reaction utility.

Copper-Catalyzed Allenylation-Isomerization Sequence of Penta-1,4-diyn-3-yl Acetates with P(O)H Compounds: Facile Synthesis of 1-Phosphonyl 2,4-Diynes

The copper-catalyzed reaction of 5-substituted penta-1,4-diyn-3-yl acetates with P(O)H compounds to efficiently give a new class of phosphonyl diynes is reported. The reaction may take place through a regioselective nucleophilic attack of phosphorus nucleophiles on Cu-allenylidene intermediates to form allenyl intermediates followed by a rapid allene-alkyne isomerization process. The synthetic utility of the obtained products is demonstrated. (Figure presented.).
