Synthesis and Radical-addition Stereochemistry of Two Trimethyl-1-pyrroline 1-Oxides as Studied by EPR Spectroscopy

A two-step synthetic route has been applied to the preparation of two five-membered ring nitrone spin traps, 3,5,5-trimethyl-1-pyrroline 1-oxide (3-Me-DMPO) and 4,5,5-trimethyl-1-pyrroline 1-oxide (4-Me-DMPO).A general method has been developed for the purification of the aqueous nitrone solution, which is suitable for the trapping of radicals present in biological processes.The EPR spin-trapping stereochemistry of 3- and 4-Me-DMPO has been investigated.The addition of the radicals .OH, RC.HOH, tetrahydrofuranyl and .OBut, to MeDMPO is stereoselective or stereospecific.Hydrogen atom addition to 3-Me-DMPO and 4-Me-DMPO gives aminoxyls 9 and 10, respectively, which each contain two non-equivalent β-protons.
