Abstract

original image

Die Stärke der Schwachen: Ein von L-tert-Leucin abgeleiteter Amin-Thioharnstoff-Katalysator (siehe Schema, grüner Kasten) vermittelt die asymmetrische vinyloge konjugierte Addition zwischen γ-Aryl- und -Alkyl-substituierten Butenoliden und den gezeigten Butenamiden und Enoaten. Rechnungen belegen, dass die bevorzugte Stereochemie eine Folge der schwachen nichtbindenden Wechselwirkungen ist, die den Übergangszustand stabilisieren.
