Descrizione

Applicazioni

(R)-(-)-4,12-Bis(diphenylphosphino)-[2.2]-paracyclophane may be used as a ligand in the following processes:

• Enantioselective reductive cyclization of 1,6-enynes via asymmetric hydrogenation in the presence of a rhodium catalyst to form alkylidene-substituted heterocycles.
• Asymmetric hydroboration of 3,3-disubstituted cyclopropenes to form 2,2-disubstituted cyclopropyl boronates.
• Asymmetric ring-opening reactions of azabenzonorbornadienes in the presence of zinc(II) triflate and palladium(II) acetate to form aminodihydronaphthalenes.

Efficient ligand for asymmetric hydrogentation of dehydroamino acids, methyl esters and keytones.
