Abstract

Abgefangen: Eine Michael ‐ Aldol ‐ artige Kaskadenreaktion, in der ein Oxoniumylid durch einen verzögerten Protonenshift abgefangen wird, führt zur Bildung mehrerer Stereozentren in einer milden Eintopfsynthese. Mit dieser Methode wurden enantiomerenreine Indanolderivate mit vier Stereozentren und einem stereogenen quartären Stereozentrum in moderaten bis guten Ausbeuten erhalten. [ABSTRACT FROM AUTHOR]

Abstract

The chiral RhI-diene-catalyzed asymmetric three-component reaction of aryldiazoacetates, aromatic amines, and β-nitroacrylates was achieved to obtain γ-nitro-α-amino-succinates in good yields and with high diastereo- and enantioselectivity. This reaction is proposed to proceed through the enantioselective trapping of RhI-associated ammonium ylides by nitroacrylates. This new transformation represents the first example of RhI-carbene-induced ylide transformation. [ABSTRACT FROM AUTHOR]
