Title: Intramolecular Interception Of Reactive Intermediates In The Raney Nickel 'generated In Situ' Reduction Of Oximes. Synthetic And Mechanistic Implications
Author: Kascheres A.
Rodrigues R.A.F.
Abstract: 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 amines 5. Mechanistic aspects of these reductions were investigated. The formation of 6 and 7 is attributed to the deactivation of the catalyst by sodium hydroxide.
