The molecule is a derivative of the naturally occurring carbohydrate D-fNCtOSe. The data reported here indicate that the ketose six-membered ring is constrained by the presence of two fused five-membered rings into the 3So conformation. These findings agree with the n.m.r.-spectroscopic results for
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
