The stereoselectivity of various Gif-type reactions was evaluated using trans-l,4-dimethylcyclohexane as a chemical probe. The results revealed that these reactions were moderately stereoselective. The outcome of the reactions was preferentially formed in the more stable equatorial configuration.
The role ofpyridine and of many substituted pyridines in Gif oxidation chemistry has been examined. In the presence of a suitable pyddine type base most of the solvent can be replaced by acetonitrile without diminishing the yield of oxidation products. The use of 4-tert-butylpyridine permits the iso
