ChemInform Abstract: Palladium‐Catalyzed Cascade Bis‐Cyclization‐Anion Capture Processes Proceeding via Allenyl‐Palladium(II) Starter Species: 1‐Vinyl‐3‐ azabicyclo(3.1.0)hexanes.

Abstract

Treatment of the enyne (I) with catalytic Pd(0) induces a series of reaction cascades including formation of an allenylpalladium species followed by 5-exo and 3-exo-trig cyclizations. Trapping of the final vinylpalladium species with anionic NaBPh4, neutral CO/MeOH or Bu3SnR produces isolated azabicyclohexanes. -(GRIGG, R.; RASUL, R.; REDPATH, J.; WILSON, D.; Tetrahedron Lett. 37 (1996) 26, 4609-4612; Mol.
