What is it about?
An α1-Dawson polyanion bearing a lateral side chain with a 4-aminopyridine end group was synthesized. This organo-POM catalyzes the addition of indenyl allyl silanes to cinnamoyl fluorides. The polyanionic framework influences the organocatalyst activity and selectivity. A moderate but nonzero chirality transfer from the chiral inorganic framework to the organic substrate was observed.
Why is it important?
The first chirality transfer from oxide surface of chiral POM to organic compounds.
