^aReaction carried out using compounds 3 (0.25 mmol) and HBPin (40 μL, 0.275 mmol, 1.1 equiv.) at room temperature under an inert nitrogen atmosphere.

^bConversions (relative to ketone 3) determined by ¹H NMR of the reaction crude.

^cConversion obtained after 4 days of reaction.

^dConversion obtained after 48 h of reaction.
