Preliminary experiments shows, that [3+2] cycloadditions reactions proceeds with full regioselectivity and high stereoselectivity. In consequence, 3,4-trans-2-methyl-3-(3,4,5-trimethoxyphenyl)-4-halo-4-nitroisoxazolidines are forming as predominantly

(2+3) Сycloadditions of gem-chloronitroethene to diarylnitrones proceed regiospecifically and lead to stereoisomeric mixtures of 3,4-cis- and 3,4-trans-2,3-diaryl-4-chloro-4-nitroisoxazolidines. The interpretation of the regiospecificity of the reac

Abstract Kinetic studies and B3LYP/6-31g(d) calculations indicate the polar nature of [2+3] cycloadditions between 1-chloro-1-nitroethene to (Z)-C-aryl-N-phenylnitrones. This is clearly confirmed by the activation parameters and the substituent and s

Abstract The analysis of reactivity indices suggests the polar nature of the [2+3] cycloaddition of a-phenylnitroethene to (Z)-C,N-diphenylnitrone. Similar conclusions can be drawn from the investigation of the reaction pathways using the B3LYP/6-31g

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 tol

Secondary α-deuterium kinetic isotope effects confirm that [2+4] cycloaddition between (E)-2-phenylnitroethene and cyclopentadiene occurs in concerted manner, on both the pathway leading to 6-endo-phenyl-5-exo-nitronorbornene and the pathway leading

B3LYP/6-31G* calculations for competing (2 + 3)-cycloaddition pathways for 2-nitropropene-1 (1) to Z-C, N-diarylnitrones (2a–e) suggest a concerted reaction mechanism. However, the results point to the strongly asymmetric nature of transition compl
