Carbon Nucleophile-Initiated Rauhut-Currier Reaction: An Atom-Economical Synthesis of Highly Functionalized Carbocycles.

A Rauhut-Currier reaction cascade is achieved in the presence of carbon nucleophiles under mild conditions. This original atom-economical transformation enables an efficient one-pot synthesis of densely substituted carbocycles from readily accessible substrates. The key promoter role of the cesium cation in the cascade process was demonstrated.
