Strategies Towards Asymmetric Conjugate Trifluoromethylation of α,β-Unsaturated Ketones and the Asymmetric Conjugate Addition of Boronates to β-Trifluoromethyl α,β-Unsaturated Ketones [PDF]
, 2014 Currently, there are no reported methods in the literature for the conjugate addition of the trifluoromethyl group to α,β-unsaturated ketones. A bulk of this thesis focused on developing a method to overcome this problem.

Chromium-catalyzed cross-coupling of methyl ketones with cyclic ketones to β-branched β,γ-unsaturated ketones are reported. Interestingly, single-crossed aldol condensation products are formed, even in reactions in which a mixture of products is possible.
