Vicinal proton-proton spin-coupling constants for methyl 5-O-acetyl-2-O-benzoyl-3,4-O-isopropylidene-fl-L-idoseptanoside (1) have led to the assignment [1] of the twist-chair conformation, °'ITC2, 3 [2], for the seven-membered ring in 1 in which the pseudo-axis of symmetry passes through C-5. Since
The structures of the title compounds (2b and 3) have been investigated in the solid state by X-ray methods. The crystals of 2b are monoclinic, space group P2,, and of 3 orthorhombit, space grtup P2,2,2,. The cell dimensions are: for 2b, a = 9.910(2), b = 11;745W, c = 11.810(3) A, /3 = 97.32(l)"; a
