The CSPVP complexes can be used in asymmetric oxidation of diols, enantioselective oxidation of alkenes, and carbon-carbon bond forming reactions, for example. The CSPVP can also be complexed with biomolecules such as proteins, DNA, and RNA, and used as nanocarriers for siRNA or dsRNA delivery.

The process involves reacting a tricyclic nitrogenous heterocycle with an allyl carbonate in the presence of a chiral palladium catalyst followed by oxidation of the olefinic bond to provide 3-heterocyclyl-1,2-dihydroxy cyclohexanes, cyclopentanes and corresponding alicyclic heterocycles. Also disclosed are methods for converting the heterocyclyl-1,2-dihydroxy cyclohexanes to 2-amino-6-(heteroaryl)cyclohexanols (and related cyclic compounds).
