It is named after its inventor, Dr. Rick Danheiser. ==Annulation== An annulation is defined as a transformation of one or more acyclic precursors resulting in the fusion of a new ring via two newly generated bonds.〔IUPAC.

ISBN 0-9678550-9-8.〕 These strategies can be used to create aromatic systems from acyclic precursors in a single step, with many substituents already in place.〔Danheiser, R L., Brisbois, R G. James, J. Kowalczyk, Miller, R. F. “An Annulation Method for the Synthesis of Highly Substituted Polycyclic Aromatic and Heteroaromatic Compounds.” J. Am. Chem. Soc. 1990, 112, 3093-3100.〕 A common synthetic annulation reaction is the Robinson annulation. It is a useful reactions for forming six-membered rings and generating polycyclic compounds. It is the combination of the Michael Addition and the Aldol Condensation reaction.〔"(Robinson Annulation )." Organic-Chemistry.
