New perspectives through enzymes: Recent breakthroughs have been achieved in the selective hydroxy functionalization of non‐activated CH and CCbonds. Enzymes turned out to be suitable catalysts for the ω‐hydroxylation of (substituted) alkanes and regioselective hydroxylation of aromatic hydrocarbons with atmospheric oxygen as the oxidant, and the asymmetric addition of water to non‐activated alkenes

decarboxylases catalyze the regio‐ and stereoselective addition of H2O across the CC double bond of hydroxystyrenederivatives yielding (S)‐4‐(1‐hydroxyethyl)phenols with up to 82 % conversion and 71 % ee. Based on structure analysis and molecular docking simulations, a catalytic mechanism for this novel enzymatic reaction is proposed.
