Semiempirical AM1 and AM1/COSMO calculations were used to examine possible pathways for the [2+3] cycloaddition of 2‑nitro‑1‑propene to (Z)‑C,N‑diphenylnitrone. These reactions proceed in the gas phase through a concerted mechanism. The effect of toluene or nitromethane as a dielectric medium results in the appearance of zwitterionic intermediates on pathways leading to 3,4-cis- and 3,4-trans-4‑methyl-4-nitro-2,3-diphenylisoxazolidines.
