Sulfamate derivatives were loaded on trityl chloride resin, and two variants of cleavage were developed for this sulfamate anchor: an acid treatment to easily restore the free sulfamate and a nucleophilic treatment to generate the corresponding phenol. In addition to loading/cleavage assays and stability experiments, a model sequence of reactions was performed with the new sulfamate anchor to show its
Oxidative rearrangements during the title reaction give 2,3 and 4 when lead(IV) acetate is used. The major products from thalIium(III) oxidation are the allylic ethers 5, 6 and 7. Oxymercuration-demercuration followed by acetylation gives 8 and 10 in addition to the ‘normal’ compound 9. The general rules previously developed for the metal salt oxidation of simple olefins depend on the nature of the

Novel derivatives of the steroid DHEA 1, a known uncompetitive inhibitor of G6PD, were designed, synthesized, and tested for their ability to inhibit this dehydrogenase enzyme. Several compounds with approximately 10-fold improved potency in an enzyme assay were identified, and this improved activity translated to efficacy in a cellular assay. The SAR for steroid inhibition of G6PD has been substantially
