Suzuki‐type cross coupling enables the direct arylative cyclization of allenic alcohols with boronic acids. This modular approach to unsaturated five‐membered O‐heterocycles proceeds in an aqueous emulsion with air as terminal oxidant. Here, the enzymatic oxidative activation of simple halide salts acts as traceless ring‐closure‐inducing event to trigger the subsequent C−C coupling. With the original protocol
