Procedure:
A 1M solution of dibutylboron triflate in dichloromethane (1.56 ml) was added to a solution of the product of step (iv) (422 mg, 1.42 mmol) in dry dichloromethane (9 ml) at 5° C. under argon, followed by diisopropylethylamine (0.295 ml, 1.7 mmol). The reaction mixture was stirred at 5° C. for 30 minutes and then cooled to -78° C. A solution of the product of step (iii) (280 mg, 1.56 mmol) in dichloromethane (2 ml) was added dropwise. The mixture was stirred at -78° C. for 30 minutes before being allowed to warm to room temperature. The reaction was quenched by the addition of pH7.2 phosphate buffer solution (1.36 ml) followed by hydrogen peroxide (0.4 ml, 30% w/v aqueous solution). The mixture was stirred for 30 minutes and then poured into water and extracted three times with dichloromethane. The combined extracts were dried (MgSO4), filtered, and evaporated. The residue was purified by column chromatography, eluting with ethyl acetate, to give methyl (7S,4Z)-7-[(S)-(1-hexylimidazol-5-yl)hydroxymethyl]-8-[(S)-4-isopropyl-2-oxo-1,3-oxazinan-3-yl]-8-oxo-oct-4-enoate (450 mg, 66% yield) as an oil; NMR 0.8-0.95(9H,m), 1.25-1.4(6H,m), 1.7-1.9(2H,m), 2.1-2.9(8H,m), 3.68(3H,s), 3.85-4.22(4H,m), 4.6-4.72(1H,m), 4.88(1H,m), 5.36-5.6(2H,m), 6.93(1H,s), 7.54(1H,s).

Procedure:
Sodium azide (1.78 g, 27.4 mmol) was added to a solution of 3-(1-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)propyl methanesulfonate (prepared as described in Part D, 24.9 mmol) in dimethylformamide (100 mL). The reaction mixture was stirred for 2.5 d and additional sodium azide (160 mg) was added. The mixture was stirred an additional 1d, then was diluted with diethyl ether (250 mL) and washed with water (3×75 mL). The combined aqueous layers were back-extracted with diethyl ether (50 mL). The combined organic layers were washed with brine (100 mL), dried over MgSO4, filtered, and concentrated to afford {[1-(3-azidopropyl)cyclohexyl]oxy}(tert-butyl)dimethylsilane (7.05 g, 95% over two steps) as a pale yellow oil. A mixture of the {[1-(3-azidopropyl)cyclohexyl]oxy}(tert-butyl)dimethylsilane (7.05 g, 23.7 mmol) and 5% palladium on carbon (0.71 g) in ethanol (100 mL) was hydrogenated at 30 psi (2.1×105 Pa) for 4 h on a Parr apparatus. The reaction mixture was filtered through CELITE filter agent, which was rinsed afterwards with dichloromethane, and the filtrate was concentrated to give 3-(1-{[tert-butyl(dimethyl)silyl]oxy}cyclohexyl)propan-1-amine as a pale yellow oil (6.57 g, 102%) that contained a trace amount of solvent.

The whole mixture was extracted with 300 mL of diethyl ether. The obtained water layer was alkalifled using a 5% aqueous solution of sodium hydroxide, and then extracted with 500 mL of ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulphate, and then concentrated under reduced pressure. A fraction possessing a low boiling point was removed from the obtained oily products to afford 18 g (yield 86%) of the desired product. Refractive index: 1.5360.
