SYNTHESIS AND STRUCTURE OF E,Z-ISOMERIC FIVE-MEMBERED CYCLIC alpha-KETO-N-METHYL NITRONES
The respective E-isomeric nitrones were obtained by methylation of the monooximes of cyclic alpha-diketones.The photochemical transformation of five-membered cyclic E-alpha-keto-N-methyl nitrones into the thermodynamically less stable Z isomers was realized for the first time, and the conditions for the preparative realization of the process were determined.Detailed investigation of the IR, UV, PMR and 13C NMR spectra and the dipole moments of the obtained nitrones showed that the dipole moments and PMR spectra are most suitable for determinig the configuration (E or Z).
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 5455-94-7
