Application

Copper(I) trifluoromethanesulfonate benzene complex can be used as a catalyst:
  • To synthesize enol-esters via copper(I) carboxylate intermediate formation.
  • In the enantioselective allylic oxidation of cyclic alkenes.
  • To prepare 2,5-disubstituted pyrrolidine derivatives from N-alkenyl, alkynyl and alkyl N-benzoyloxysulfonamides via the sulfonamidyl radical formation.

It can also be used in combination with amino acid-based chiral phosphine ligands to catalyze asymmetric conjugate additions of alkylzincs to acyclic α,β-unsaturated ketones, affording β-alkylcarbonyls in high yield and with excellent enantioselectivity.

The first enantioselective synthesis of erogorgiaene (1), an inhibitor of mycobacterium tuberculosis, is disclosed. The total synthesis highlights the utility of asymmetric conjugate additions (ACA) of alkylzincs to acyclic alpha,beta-unsaturated ketones catalyzed by peptidic phosphine ligands and (CuOTf)(2).C(6)H(6).
