Reaction Steps

To a mixture of (7S,10S)-7-isopropyl-4,4-dimethyl-10-vinyl-9-oxa-16-thia-3,6,13,18-tetraazabicyclo[13.2.1]octadeca-1(17),15(18)-diene-2,5,8,12-tetraone (20 mg, 0.047 mmole) in 2 mL 1,2-dichloroethane was added 4-bromo-1-butene (25.6 mg, 0.19 mmole) and Zhan-1 catalyst (3.2 mg, 0.0047 mmole). The mixture was briefly degassed and then heated in a sealed tube at 85° C. overnight. The crude product was concentrated and passed through a silica gel plug to get a mixture of the desired product and recovered starting material (2:1 ratio). It was further purified by reversed phase chromatography, eluted with 0˜80% water/CH3CN to get the desired product (8 mg, 32% yield).
