The first template assisted meta-hydroxylation strategy and its use in the synthesis of resveratrol precursor and QR-activity inducer with detailed experimental and in-silico mechanistic understanding. meta-Hydroxylated cores are ubiquitous in natural products. Herein, we disclose the first template assisted meta-hydroxylation reaction. Experimental and in silico studies helped us to gain valuable mechanistic insights, including the role of the hexafluoroisopropanol (HFIP) solvent, during C–H hydroxylation. The reactive intermediates, prior to the C–H activation, have been detected by spectroscopic techniques. Additionally, the C–O bond formation has been extended to meta-acetoxylation. The preparation of a phase II quinone reductase activity inducer and a resveratrol precursor illustrated the synthetic significance of the present strategy.
