Spartan'06 (Wavefunction, Inc.) was used for the calculation. A Monte Carlo conformation search was performed by using the MMFF force field to find the lowest-energy conformation, which was then used as an initial structure for the ab initio geometry optimization (RHF/6-31G**). No symmetry contraints were used in the calculations
