DOI: 10.1055/a-2644-2089
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… read more here.
