Graphical Abstract

Einen einfachen Zugang zu axial-chiralen Phthaliden mit ein oder zwei Oxymethylen-Funktionalitäten bietet eine enantioselektive Alkincyclotrimerisierung in Gegenwart des kationischen Komplexes [RhI{(S)-H8-binap}]+. Die axiale Chiralität wird während der Bildung des Benzolrings mit hoher Enantioselektivität eingeführt.
