Abstract

1 min read

Auf das Substrat abgestimmt: Chirale Liganden L* und chirale Anionen, wie in (S)-TriP Ag, wurden in Gold(I)-katalysierten enantioselektiven intramolekularen Additionen von Hydrazinen und Hydroxylaminen an Allene eingesetzt. Diese komplementären Ansätze ebnen den Weg zu den Titelverbindungen in chiraler Form. PNB=para-Nitrobenzoyl.
