The aim of this study was to explore histone deacetylase inhibitory and antioxidant activities of natural products from ginger and their semi-synthetic derivatives. Two major phenolic compounds, [6]-gingerol and [6]-shogaol along with three minor phenolic compounds including [6]-gingerdione, 1-dehydro-[6]-gingerdione and [6]-gingerdiol were isolated and tested against histone deacetylase in HeLa nuclear

γ-selective hydroxylation of α,β,γ,δ-unsaturated carbonyl compounds and its application to syntheses of (±)-6-hydroxyshogaol and related furanoids
α,β,γ,δ-Unsaturated carbonyl compounds were converted regioselectively into γ-hydroxy-α,β-unsaturated carbonyl compounds by reduction-oxygenation with molecular oxygen and triethylsilane in the presence of cobalt(II) porphyrin as a catalyst followed by treatment with trimethyl phosphite. (±)-6-Hydroxyshogaol and related furanoids isolated from ginger were synthesized via this method.
