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
In the course of recent investigations '-4 in this series, we developed a oneflask synthesis of triacetalated, acyclic aldohexoses by use of 2,2-dialkoxypropanes or l,l-dialkoxycyclohexanes in the presence of p-toluenesulfonic acid. As shown in a preceding paper', one of the triacetals obtained from
