実験手順
A solution of tert-butyl (S)-1-(4-bromophenyl)ethyl((E)-4-((R)-tert-butylsulfinylimino)-4-phenylbutyl)carbamate (1.97 g, 3.59 mmol) in dry THF (60 mL) was cooled to −78° C. A solution of 2-methylallylmagnesium chloride (0.5M in THF, 14.4 mL, 2 equiv) was added slowly. After 2 h, the mixture was warmed to rt and stirred for 1 h. LC-MS found reaction completed. The mixture was quenched with satd aq NH4Cl (10 mL), diluted with ether (100 mL), washed with water (30 mL), brine (25 mL), dried over Na2SO4. Filtration and concentration gave crude tert-butyl (S)-1-(4-bromophenyl)ethyl((S)-4-((R)-1,1-dimethylethylsulfinamido)-6-methyl-4-phenylhept-6-enyl)carbamate (2.30 g) which was used for next steps without further purifications. LC-MS Method 1 tR=2.53 min, m/z 605, 607(M+1).
