Reduction of oximes 4, obtained from 1,5 di-hydro-2H-pyrrol-2-ones 3, with Raney nickel “generated in situ” afforded pyrrolo [3,2b] pyrrolone derivatives 6 and 7 and, in some cases, amines 5. The reduction of 4 with W7 Raney nickel afforded only

New pyrrolizidine derivatives 6 and 7 were prepared from the 1, 5-dihydro-2H-pyrrol-2-one 3a via an acidic intramolecular aldol condensation in 16% and 42% yields, respectively. Compound 6 was obtained by dehydration of 7 with p-toluenessulfonic acid
