Highly Effective Vinylogous Mukaiyama− Michael Reaction Catalyzed by Silyl Methide Species Generated from 1, 1, 3, 3-Tetrakis (trifluoromethanesulfonyl) propane
Silyl methide species in situ generated from 1, 1, 3, 3-tetrakis (trifluoromethanesulfonyl) propane (Tf2CHCH2CHTf2) performed as an excellent acid catalyst for the vinylogous Mukaiyama− Michael reaction of α, β-unsaturated ketones with 2-silyloxyfurans. Notably, the
