Ligand bite angle-dependent palladium-catalyzed cyclization of propargylic carbonates to 2-alkynyl azacycles or cyclic dienamides.

Ligand bite angle-dependent palladium-catalyzed cyclization of propargylic carbonates to 2-alkynyl azacycles or cyclic dienamides.

The regioselectivity of the palladium-catalyzed cyclization of propargylic carbonates with sulfonamide nucleophiles is critically dependent on the bite angle of the bidentate phosphine ligand. Ligands with small bite angles favor attack on the central carbon atom of an allenylpalladium intermediate...
