Acid-catalyzed reduction of a sulfenate ester by iodide

Reaction of ethyl benzenesulfenate with iodide ion in aqueous acid results in formation of diphenyl disulfide and iodine and is of first order in both acid and iodide concentrations.

Anomeric activation of thioglycosides and preparation of deoxyglycosides using polymer-bound iodate(I) complexes

New thiophilic polymer-bound haloate(I) complexes are presented which are well suited for the polymer-assisted solution-phase activation of 2-deoxythioglycosides. In the presence of alcohols 2-deoxyglycosides are obtained in yields between 60 and 95%. Isolation of the target glycosides is further simplified by removing the byproduct diphenyldisulfide by reductive work-up. Here also a polymer-bound reagent, namely borohydride exchange resin, served as a tool for sequestering the sulfur-containing impurities.

Process for the preparation of rose oxide

Rose oxide, or 2-[2-methyl-prop-l-en-l-yl]-4-methyl-tetrahydropyrane, a fragrant chemical specialty, is prepared efficiently by a novel process which consists in five reaction steps and uses citronellol as starting material.
