    • The stable conformers 27A and 27B of 27 were generated by a molecular modeling search with AMBER* force field with the GB/SA solvation model for water using MacroModel V 6.0. The difference in potential energies between 27A and 27B is estimated to be 0.1 kcal/mol. A PM3 calculation with a polarized continuum model (water, ε=78.4) also gave stable structures similar to 27A and 27B.: (a) Still, W. C.; Tempczyk, A.; Hawley, R. C.; Hendrickson, T. J. Am. Chem.
