Initial 3D structures of compounds 2a, 2b, and 4 were generated using a protocol of CAESAR Generate Conformations and optimized using a protocol of CHARMm (version 35.1) Minimization available within Discovery Studio software (version 2.5.5; Accelrys Inc:2009;2009). LUMOs of equilibrium geometry of 2a, 2b, and 4 were calculated using the HF 3-21G(*) method of SPARTAN '04 software (version 1.0.3; Wavefunction Inc.: 2005).
