Spirocyclic indazoles were designed as potential ligands for the glucocorticoid receptors (GRs). A short and efficient synthetic sequence was developed allowing the preparation of pure diastereomeric spirocyclic analogs of fluorocortivazol. Our studies also revealed a new application of Burgess reagent leading to a ring expansion. The structures and conformations of several key intermediates and products were confirmed by single crystal X-ray diffraction analysis. Conformational assignments were also supported by DFT calculations. As a proof of concept we tested the affinity of diastereomeric compounds 13b and 14b for the GRs. Rewardingly, it was found that 14b showed a promising IC50 of 27 nM.

Both the enantiomers of cyclohex-2-ene-spirocyclohexane-2',4-dione (S-I and R-I) have been obtained starting from 2-formylcyclohexanone under two different sets of reaction conditions using the same chiral auxiliary S-proline.
