Аннотация

The regio- and stereoselectivity of [3+2] cycloaddition reactions of (Z)-1-(anthracen-9-yl)-N-methyl nitrone with analogs of trans-β-nitrostyrene were studied within the molecular electron density theory at the B3LYP/6-31G(d) and MPWB95/6-311G(d,p) theory levels. Analysis of the reactivity indices for presented reactions suggests that nitrone participates as nucleophile, while studied nitroalkenes play a role of electrophiles. According to electron localization function and conceptual density functional theory, kinetic and thermodynamic aspects of processes as well as analysis of all critical structures, the most favored reaction path is the formation of (3RS,4RS,5SR)-3-(anthracen-9-yl)-5-aryl-2-methyl-4-nitroisoxazolidine, independently of simulated solvent.
