Reaction Steps

A mixture of (S)-5,5-dimethyl-1-hexyn-4-ol (1.96 g 16 mmol), triethylamine (4.5 ml, 32 mmol) and dry dichloromethane (30 ml) was cooled to 0° C. under a nitrogen atmosphere. Triethylsilyl trifluoromethanesulphonate (5.4 ml, 24 mmol) was slowly added and the mixture stirred at 0° C. for a further 40 min. The mixture was treated with saturated sodium bicarbonate solution (60 ml) and the organic layer separated. The aqueous layer was extracted with dichloromethane (3×20 ml) and the combined dichloromethane extracts dried (MgSO4) and evaporated. The residue was purified by column chromatorgaphy (silica eluted with Petroleum ether 40-60°) to yield the title compound 3.55 g (95%).
