Reaction Steps
To (3aR,4R,7R,9R,10R,11R,13 R,15R,15aR)-3a-({[tert-butyl(dimethyl)silyl]-oxy}methyl)-4-ethyl-11-methoxy-7,9,11,13,15-pentamethyl-2,6,8,14-tetraoxo-1-[4-(4-pyridin-3-yl-1H-imidazol-1-yl)butyl]tetradecahydro-2H-oxacyclotetradecino[4,3-d][1,3]oxazol-10-yl 3,4,6-trideoxy-3-(dimethylamino)-D-xylo-hexopyranoside (1 eq) in tetrahydrofuran was added acetic acid (2 eq) and tetrabutylammonium fluoride/1.0M in tetrahydrofuran (2 eq). After standing for 48 hours, ethyl acetate was added and the solution was washed with NaHCO3(sat.), NaCl(sat.), dried over MgSO4, filtered, and concentrated. Purification by RP HPLC afforded (3aR,4R,7R,9R,10R,11R,13R,15R,15aR)-4-ethyl-3a-(hydroxymethyl)-11-methoxy-7,9,11,13,15-pentamethyl-2,6,8,14-tetraoxo-1-[4-(4-pyridin-3-yl-1H-imidazol-1-yl)-butyl]tetradecahydro-2H-oxacyclotetradecino[4,3-d][1,3]oxazol-10-yl 3,4,6-trideoxy-3-(dimethylamino)-D-xylo-hexopyranoside (48% yield) as a white solid. MH+(828.50).
