Procedure:
To a solution of N-t-butoxycarbonyl-sarcosine (50 g; 0.264 mol) in 700 ml of benzene was added 1,8-diazabicyclo[5.4.0]-undec-7-ene (DBU; 40.19 g, 0.264 mol) in one portion. To the above clear solution was added 74.84 g (0.528 mol) of methyl iodide in one portion and the resulting clear solution was allowed to reflux for 7 hours. After adding additional methyl iodide (16 ml), the reaction mixture was refluxed with stirring, cooled to room temperature, and stirred overnight. The reaction mixture was filtered, the residue washed with ether, and the combined filtrate was washed with water, saturated sodium bicarbonate solution, and brine. The resulting organic layer was dried over sodium sulfate, filtered, and concentrated in vacuo to afford 46.38 g (86.4%) of N-t-butoxycarbonyl-sarcosine methyl ester as a yellow oil.

Procedure:
A mixture of Zn powder (1.65 g, 25.0 mmol), triphenylphosphine (6.54 g, 25.0 mmol), and CBr4 (8.30 g, 25.0 mmol) in dry CH2Cl2 (40 mL) was stirred at ambient temperature. After 24 hours, 2,5-dimethoxy-tetrahydrofuran-3-carboxaldehyde (2.00 g, 12.5 mmol) was added and an exothermic reaction ensued. After 30 minutes, pet ether (100 mL) was added and the resultant upper layer separated. The lower layer was twice diluted with CH2Cl2 (50 mL) and pet ether (50 mL), and the upper layer reserved. The combined upper layers were combined, passed through a pad of SiO2, and concentrated under reduced pressure at 30° C. or below to give 2.18 g (55%) of 3-(2,2-dibromoethenyl)-2,5-dimethoxytetrahydrofuran as a volatile colorless oil, which was a mixture of diastreomers by 1H NMR and used immediately without further purification.

Procedure:
Sodium hydride (60% dispersion in mineral oil, 31.5 g, 1.28 eq.) was slowly added under nitrogen atmosphere to a solution of N-methyl-2,2,2-trifluoroacetamide (100 g, 1.28 eq.) in DMF (500 mL) at 0° C. The reaction mixture was stirred for 90 min at 0° C., and then 6-bromo-1-hexene (100 g, 1 eq.) was added dropwise over 45 min. The reaction mixture was allowed to warm up to room temperature, and stirred for 3 days at room temperature. The reaction mixture was then poured into water and extracted tree time with EtOAc. The combined organics layers were dried over anhydrous sodium sulphate and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel to produce compound 31a as colorless oil in 56% yield.
