hydroxyl‐directed method allows for the diastereoselective access to a wide variety of masked β‐hydroxy ketones, starting from readily available aliphatic and aromatic oximes, homoallylicalcohols and monoprotected homoallylic diols. The utility of the prepared Δ2‐isoxazolines as polyketide building blocks is demonstrated by their ready conversion into the corresponding β‐hydroxy ketones. The anti‐
