Finding the Best Proposed Mechanism for Ugi Multi-Component Reaction by DFT Study
The one-pot four-component condensation of benzoic acid (R1), aniline (R2), benzaldehyde (R3), and 2-isocyano-2-methylpropane was investigated at the B3LYP/6-311G** level to explore the reaction mechanism as a theoretical study. All routes were studied and structure of intermediates (IM) was optimized and all of the respective transition states (TS) were found. The calculation results proved that the proposed mechanism consists of eight steps that rate determining the state is nucleophilic attack of isocyanide to benzaldehyde.
期刊介绍：
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
