Participants

Reaction Steps

To a solution of 6.59 g of 2-mercapto-benzothiazole and 7.87 g of triphenylphosphine in 65 ml of THF was added at 0° a solution of 9.25 g of (2E,9Z)-12,12,12-Trifluoro-7,7-dimethyl-11-triethylsilanyloxy-11-trifluoromethyl-dodeca-2,9-dien-1-ol in 35 ml of THF which was followed by addition of 8.09 g of diisopropyl azodicarboxylate over 20 min and stirring was continued at 0° for 1 h after which time t.l.c. indicated completion of the reaction. The mixture was washed with sat. aqueous NH4Cl- and NaCl-solution, the organic layer was dried over MgSO4 and evaporated. The residue was chromatographed on silica with hexane/AcOEt 9:1 to give 11.13 g of the pure (t.l.c.) title compound as a yellow oil. IR (neat): 1663w (C═C). MS (EI): 611/7 (M).
