Abstract

This review presents recent advancements in gold- and platinum-catalyzed [2+2+2] cyclization involving an alkyne (or an allene), an alkene, and a carbonyl compound. These transformations are referred to as Prins-type cyclization, by analogy with the classical Prins reaction, in which an alkene reacts with an oxonium species derived from a carbonyl compound. In the metal-catalyzed versions, the carbonyl engages with a metal carbene intermediate—either directly at the carbene center or at another electrophilic site within a strained ring (e.g., cyclopropane or cyclobutane)—to generate an oxonium species that reacts with an unsaturated partner to afford cyclic products. Both intra- and intermolecular variants will be discussed, along with enantioselective developments and applications toward complex molecules and natural products.
