SYNTHESIS OF PYRROLE DERIVATIVES VIA DEOXYGENATION OF 4H-1,2-OXAZINES BY IRON CARBONYLS

Article abstract of DOI:10.1246/cl.1981.869

The reaction of 5,6-dihydro-4H-1,2-oxazines, which are derived from α-bromooximes and enamines, with iron carbonyl complexes such as Fe3(CO)12 and (C2H5)3NH gives pyrrole derivatives in high yields, accompaning deoxygenation from the oxazines.
