Herein we describe a combined experimental/theoretical study on the effects of substituents on regio- and stereoselectivity in intramolecular 1,3-dipolar cycloadditions of nitrones and alkenestethered by benzimidazoles. By employing a large substituent at position R2 or R3, complete selectivity was achieved for either the fused or bridged cycloadduct, respectively. In addition, these cycloadducts

Internal alkynes have been used in combination with tosylamides and the Narasaka leaving group to form tetra(hetero)substituted enamines in an aminopalladationcascade reaction. The cascade was terminated either intramolecularly by a Heck reaction or intermolecularly in a Suzuki-type reaction with a boronic acid.

The reaction of 1-bromomethyl-1-cycloalkenes and acetylenes in the presence of tetracarbonylnickel affords moderate to good yields of spirocyclopentenones in a regio and stereoselective process.
