(A) H-bond–assisted C–H activation of alcohols. Shown is a proposed mechanistic pathway for the C-alkylation of alcohols with Michael acceptors. SET, single-electron transfer. (B) Evaluation of hydrogen-bonding catalysts. Yield determined by means of 1H NMR, using an internal standard. (C) Selected scope of simple alcohol addition to methyl acrylate. Only products are shown; experimental conditions are as in (B). Isolated yields are reported.
