An ylide transformation of rhodium(I) carbene: enantioselective three-component reaction through trapping of rhodium(I)-associated ammonium ylides by β-nitroacrylates

Angew Chem Int Ed Engl. 2014 Nov 24;53(48):13136-9. doi: 10.1002/anie.201407740. Epub 2014 Oct 5.

Abstract

The chiral Rh(I)-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 Rh(I)-associated ammonium ylides by nitroacrylates. This new transformation represents the first example of Rh(I)-carbene-induced ylide transformation.

Keywords: ammonium ylide; carbenes; multicomponent reactions; rhodium; β-nitroacrylates.
