The title compound (9S)-2′-O-benzoyl-9,11-[carbonylbis(oxy)]-9-deoxo-5-O-(-D-desosaminyl)-12,21-anhydro-9-hydroxyerythronolide A 1 was synthesized. The crystal structure of the acetone solvate of 1, C37H55NO11·C3H6O, was determined by single-crystal X-ray diffraction analysis. It belongs to monoclinic system, space group P21 with a = 14.4691(10), b = 8.2626(6), c = 17.5990(11) , β = 94.167(1)°, V = 2098.4(2)3, Mr = 748, Z = 2, Dc = 1.184 g/cm3, μ = 0.087 mm-1, F(000) = 808, S = 1.026, R = 0.0542 and wR = 0.1322 for 3331 observed reflections (I > 2σ(I)). In the solid state, molecules of 1 are linked into spirals along the b axis by O(25)- H(25)···O(29) intermolecular hydrogen bond.
