β-Phosphorylated five-membered ring nitroxides: synthesis and ESR study of 2-phosphonyl-4-(hydroxymethyl)pyrrolidine aminoxyl radicals
摘要:
Intramolecular aminomercuration of the alkenyl alpha-amino phosphonate 6 followed by sodium borohydride reduction leads to the diethyl (4-(benzyloxymethyl)-2,5,5-trimethylpyrrolidinyl)-phosphonate 7. Oxidation of the phosphonates 7 and 8 with 3-chloroperbenzoic acid led to the stable 2-phosphonylpyrrolidinyl aminoxyl radicals 9 and 10 bearing a 4-(hydroxymethyl)substituent.
