- 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.
