Graphical Abstract

Metallfreie Katalyse: Hoch funktionalisierte Moleküle mit zwei benachbarten Stereozentren sind mit einem käuflichen Organokatalysator einfach, in hoher Ausbeute und mit hoher Enantio- und Diastereoselektivität zugänglich (siehe Schema). Die leicht zu entfernende Boc-Schutzgruppe im Produkt ist ein zusätzlicher Vorteil dieser Methode.
