Carbene-catalyzed direct functionalization of the β-sp3 -carbon atoms of α-chloroaldehydes
A direct functionalization of the β-sp3 carbon atom of α-chloro aldehyde has been developed. The reaction starts with the addition of a carbene catalyst to α-chloroaldehyde to eventually form the homoenolate intermediate. This overall redox-neutral process successfully converts the otherwise inert β...

| Summary: | A direct functionalization of the β-sp3 carbon atom of α-chloro aldehyde has been developed. The reaction starts with the addition of a carbene catalyst to α-chloroaldehyde to eventually form the homoenolate intermediate. This overall redox-neutral process successfully converts the otherwise inert β-sp3 -carbon atom of the aldehyde substrate to a nucleophilic carbon atom for asymmetric reactions. This study constitutes the first success in activating α-chloroaldehydes to generate homoenolate intermediates by carbene organic catalysis and shall encourage further explorations in using organic catalysis for transforming inert chemical bonds. |
