What is Calculation of molecular rotation by summation of partial conformational contributions : Part II. Rotations of the 1,6-anhydro-deoxy-β-d-hexopyranoses, 2,7-anhydro-β-d-heptulopyranoses, and their acetates about?

The optical rotations of two families of compounds, both having the l,6anhydro-P-D-hexopyranose structure as the fundamental skeletal umt, have been expressed as algebraic summations of empirical rotatory contributions from varrous conformational elements of asymmetry. The calculations have been made for 1,6anhydro-monodeoxy-/?-D-hexopyranoses and their diacetates, and for the 2,7-anhydro-@-D-heptulopyranoses and their tetraacetates, by using terms calculated' for the parent l,6-anhydro-#I-D-hexopyranoses and four new terms to describe interactions previously untreated. The calculated rotations are in satisfactory agreement with constants reported in the literature. and indicate conformational uniformity throughout the entire class of examples.
