Under the auspices of Bacchus! Acutissimins, natural flavano‐ellagitannins, occur in oak‐aged wine as a result of a diastereoselective condensation reaction of the flavan‐3‐ol catechin, a component of grapes, with the C‐glucosidic ellagitannin vescalagin, found in oak. The acutissimins are further converted into natural mongolicains and analogues of camelliatannin G in a remarkably chemoselective fashion by simple aerobic oxidation.
