Procedure

1.55 ml (773 μmol) (0.5M in THF) of 9-borabicyclo[3.3.1]nonane were added to a solution of 50 mg (77 μmol) of tert-butyl (S)-6-tert-butoxycarbonylamino-2-[3-((9S,12R)-9-isopropyl-11-oxo-2,7-dioxa-10-azabicyclo[12.2.2]octadeca-1(17),4,14(18),15-tetraen-12-yl)ureido]hexanoate (8-1B) in 1.5 ml of THF, and the mixture was stirred at RT overnight. Addition of 250 μl (1.49 mmol) of 6N sodium hydroxide solution and 207 μl (1.83 mmol) of hydrogen peroxide was followed by extraction with dichloromethane. The organic phase was washed with saturated sodium chloride solution, dried over Na2SO4, filtered and concentrated. The residue was purified by preparative HPLC.
