One reaction of this type involves an alkoxide intermediate formed by enolate reacting with an ester and results in a beta-ketoester; that reaction has an intramolecular version named for Dieckmann. Besides the Claisen and aldol varieties, other examples include phosphorylation, glycosylation, and polypeptide synthesis. Used to describe reactions between two molecules to form a single larger molecule combined with the loss of a smaller molecule, for 10 points, give this term which also describes a change of matter from the gaseous phase to the liquid phase.
