The reaction of trimethyl phosphite with diphenylacecylone in the presence of methanol results in the reduction of the diphenylacecyclone carbonyl group.Dimethyl 7,9-diphenyl-6aH-cyclopent-acenaphthylen-8-yl phosphate, dimethyl 7,9-diphenyl-8H-cyclopen

ADDITION OF PHTHALIMIDO NITRENE TO SUBSTITUTED CYCLOPENTADIENES

The aziridines 3, 3a and 3b obtained by the cycloaddition of phthalimidonitrene to cyclopentadiene derivatives 2, 2a and 2b undergoes facile ring expansion, when treated with sodium hydride to give substituted pyridine derivatives 4, 4a and 4b respectively.Hydrazinolysis of the aziridines gives the cyclopentadiene derivatives through the intermediacy of N-aminoaziridines 5, 5a and 5b.Oxidation of the aziridines 3, 3a with lead tetraacetate gives the aziridine 6 and 6a.
