Özet
Phenylboronic acids are used as synthetic intermediates in organic synthesis Suzuki-Miyaura reaction is important for the synthesis of many inhibitors of serine proteases. Geometry optimization was performed for the eight possible conformations of 3-formylphenylboronic acid (3FPBA) and 4-formylphenyl-boronic acid (4FPBA) using the DFT/B3LYP method with the 6-311++G(d,p) basis set. According to the theoretical calculation results, C3 conformation was found more stable than other conformations. The compounds 3FPBA and 4FPBA were investigated by using FT-IR (4000-400 cm(-1)), dispersive Raman (4000-40 cm(-1)) spectroscopy and theoretical DFT/B3LYP/6-311++G(d,p) calculations. The calculation results have been compared with observed values, which agree with each other. Natural bonding orbital (NBO) analysis was performed to analyze the hyper-conjugative stability of the molecule, molecular orbital interaction and charge delocalization. Frontier orbitals (FMOs) were identified to describe the reactivity of the title molecules. The calculated UV-Vis absorption spectrum was analyzed using the TD-DFT approach. Furthermore, molecular docking studies of 3FPBA and 4FPBA compounds were performed with anti-apoptotic proteins. Our finding shows compounds 3FPBA and 4FPBA have same binding affinity with each of anti-apoptotic proteins.
