Advances in asymmetric catalysis using the bifunctional cinchona alkaloid/thioureas enabled an umpolung of the classical Cβ reactivity of 3-alkylidene oxindoles, thus allowing the development of the first and sole example of a direct, organocatalytic asymmetric vinylogous Michael (AVM) reaction with nitroolefins.

Abstract

Advances in asymmetric catalysis using the bifunctional cinchona alkaloid/thioureas enabled an umpolung of the classical Cβ reactivity of 3-alkylidene oxindoles, thus allowing the development of the first and sole example of a direct, organocatalytic asymmetric vinylogous Michael (AVM) reaction with nitroolefins.
