In contrast to the corresponding hydroxyiodination reactions, the reaction of acetoxycyclohex-2-ene 1 with N-PSP in the presence of water shows little regiocontrol, but is highly diastereoselective. However, the same reaction of the (R)-phenylglycinate derivative of (±)-cyclohexen-3-ol is highly diastereoselective, and regioselective. A hydrogen-bonding interaction is proposed to rationalize these
