Graphical Abstract

Von Eninen zu Spirocyclen: Eine Rhodium-Dien-katalysierte Addition von Natriumtetraarylboraten an 2-Cycloalken-1-one mit einer anhängenden Alkineinheit führt zu Spirocarbocyclen. Dabei werden zwei neue C-C-Bindungen durch das Tetraarylborat gebildet, und der chirale Dienligand sorgt für den hoch enantioselektiven Aufbau quartärer Kohlenstoffspirozentren.
