実験手順

Methyl(2S)-2-(tert-butoxy)-2-[(22S)-17-fluoro-4,22,28-trimethyl-5-(prop-1-en-2-yl)-21,27-dioxa-1,7,34-triazahexacyclo[26.2.2.16,9.110,14.02,7.015,20]tetratriaconta-2,4,6(34),8,10(33),11,13,15(20),16,18-decaen-3-yl]acetate (45 mg, 0.064 mmol, 1 equiv) was dissolved in dioxane (1934 μl) and water (645 μl). To this solution was added sodium periodate (444 mg, 2.076 mmol, 3.5 equiv) and 4% osmium tetraoxide (372 μl, 0.030 mmol, 0.05 equiv). The mixture was stirred at r.t. for 2 hours. Yellow solid was observed in the meantime. To the mixture was added water (20 mL) and EA (20 mL). The aqueous layer was separated. the organic layer was washed by brine, dried over MgSO4, filtered and concentrated to give a yellow oil, which is used as is for the next reaction. LCMS (ESI, M+1): 700.3.
