Synthesis of (R)-2,3-Dihydro-2,5-dimethyl-2-isopropylfuran

The synthesis of (R)-2,3-dihydro-2,5-dimethyl-2-isopropylfuran (1), an insect pheromone, via a 1,3-oxathiane is reported.Key steps are the preparation of (S)-2,3-dimethylbutane-1,2-diol (7) from isobutyryloxathiane 5 and reaction of lithiated acetone dimethylhydrazone with tosylated diol 8.NMR spectra of the key tautomeric precursors, 2/2'/3, to 1 have been analyzed in detail, and the enantiomeric excess of these precursors was determined by a chiral shift 13C NMR experiment.
