Carboxylic Acids and their Derivatives
Lactones Lactides, Lactams, and Lactims Rule C-474 474.1 - Lactides are intermolecular cyclic esters formed by self-esterification from two or more molecules of a hydroxy acid. They are
named as heterocycles by the rules of Section B unless the hydroxy acid has a trivial name. In the latter case the syllables "-ic acid'' in that trivial name are replaced by "-ide'' and a prefix
"di-" or "tri-", etc., is added to denote the number of molecules involved.
See Recommendations'93 R-5.7.5
