摘要： The present invention relates to a process for preparing a lactone. The process comprises the steps of reacting an aldehyde with an organic halide in a carbon chain extension reaction to form an alcohol compound comprising a functional group capable of allowing for carbonylation of said alcohol compound, and then reacting said alcohol compound in a carbonylation reaction to form an hydroxycarboxylic acid; and cyclising the hydroxycarboxylic acid to produce the lactone.
