Relationship of the anionic behavior of unsaturated medium-ring alcohols to structure. Generation and antarafacial cyclization of coiled 8.pi.-electron carbanions
Controlling Mode Selectivity in Palladium-Catalyzed Bisdiene Carbocyclizations: Optimizing for Cyclization-Trapping over Cycloisomerization
摘要:
Screening combinations of five catalyst precursors with 13 phosphorus ligands identified cyclization catalysts that favor carbocyclization-trapping with N-hydroxyphthalimide over a competing cycloisomerization mode.
