The oxidation of 4,5,5-trimethyl-1-pyrroline 1-oxide (I) with lead tetra-acetate gives 1-acetoxy-4,5,5-trimethyl-2-pyrrolidone (IIb) in 64% yield; with an excess of potassium permanganate the major product was 3,4-dimethyl-4-nitropentanoic acid (IVa). 1-Hydroxy-4,5,5-trimethyl-2-pyrrolidone (IIa) was cleaved upon treatment with potassium permanganate or lead tetra-acetate and gave novel compounds derived
