A carboxylic function with a leaving group in the ω-position can form a lactone via an intramolecular substitution process (Scheme 68). The leaving group might be a halide, an epoxide, a hydroxy group, or a double bond; in the extreme it might be a carbocation. Well-known reactions in this regard include the halolactonization of ω-unsaturated carboxylic acid derivatives, the cyclization of ω-bromo carboxylic acids, and the Mitsunobu lactonization.
