Abstract

Bi(OTf) 3 -Catalyzed Cycloisomerization of Aryl-Allenes. -Cyclohydroarylation or tandem intramolecular cycloaddition reactions produce different types of polycycles. The reaction is mostly controlled by the temperature. Intermolecular tandem Friedel-Crafts allylation/alkylation reaction leads to a functionalized indan (XV). -(LEMIERE, G.; CACCIUTTOLO, B.; BELHASSEN, E.; DUNCAH*, E.; Org.
