Abstract The convenient one-pot method for phosphoryloxylactonization of alkenoic acids was reported: when (diacetoxyiodo)benzene, various 4-pentenoic acids and phosphates were mixed in CH3CN at room temperature, phosphoryloxylactones were obtained in good to excellent yields in short times, some had two diastereoisomers.

A novel and convenient catalytic method for phosphoryloxylactonization of pentenoic acids is available: the cyclization of 4-pentenoic acids with phosphates using iodobenzene as a recyclable catalyst in combination with m-chloroperbenzoic acid as the terminal oxidant was easily carried out in CF3CH2OH at room temperature, giving phosphoryloxylactons in good yields, some of them had two diastereoisomers.

Using ammoniumiodide as a catalyst and m-chloroperbenzoic acid as the oxidant, a novel and efficient procedure has been developed for phosphoryloxylactonisation of alkenoicacids in CH3CN at room temperature, which provides the corresponding phosphoryloxylactones in good yields. In this protocol, it is proposed that ammoniumiodide catalyst is first oxidised to hypoiodous acid, which reacts with the
