Hydrogen iodide allylic compounds

Allyl-/-butyltrithiocarbonates (236), which are obtained from readily available allyl halides by a multi-step reaction with sodium t-butyltrithiocarbonates, can be cyclized with concomitant loss of hydrogen iodide and isobutylene using elemental iodine to afford 1,3-dithiolane-2-thiones (237) ( heme 48) treatment of (237) with pyridine again results in a loss of hydrogen iodide and (238) is formed. Compound (238) can be isomerized using trifluoroacetic acid and (239) is obtained <80JOC2959>. [Pg.634]
