DIASTEREOSELECTIVE DESULFURIZATION OF 5,6-DIHYDRO-1,4-DITHIINS - SYNTHESIS OF MUSCALURE FROM MUSCA-DOMESTICA L

A procedure is reported for the chemo- and stereo-selective sulfur rem oval from 5,6-dihydro-1,4-dithiins which completes the pathway to synt hesize cis configurated olefins from carbonyl compounds. A four step s ynthesis of (Z)-9-tricosene (muscalure) with the dithiin moiety servin g as the penultimate olefin precursor is also reported as an example o f the proposed synthetic strategy.
