Bromination and bromohydroxylation of oxazolidinones derived from cyclohexadiene have been studied in order to synthetize (±)-epibatidine 18. Bromohydroxylation of compound 2 led to a polyfunctionalized halohydrin 11a which could be further cyclized to azabicyclo[2.2.1]heptan-2-one 16 already described as a precursor of epibatidine 18.
Hexafluoroisopropanol (HFIP)-prompted rearrangement of N-phenoxysulfonamides for the direct assembly of ortho-sulfonamide phenols: A combined experimental and computational study

Enantioselective ring-contraction reactions have not been widely reported. We have developed an enantioselective ring contraction of 5,6-dihydro-2H-benzo[b][1,4]oxazocines, affording enantiomerically enriched 3,4-dihydro-2H-1,4-benzoxazine derivatives as
