Abstract
A number of previously unknown 5-alkylpyrrolidones-2 and 1-methyl-5-alkylpyrrolidones-2 were synthesized by reductive amination of the ethyl esters of 8-ketocarboxylic acids with ammonium and methylamine in the presence of Raney nickel, ruthenium dioxide, or Raney nickel activated with ruthenium. The highest yields of 5-alkylpyrrolidones-2 were obtained when ruthenium dioxide was used as a catalyst. The acetyl derivatives of 5-alkylpyrrolidones-2 are described.
