  • Process for preparing benzomorpholine derivatives by hydrogenating o-nitrophenoxy carbonyl compounds
    Patent number: 8252924
    Abstract: A process for preparing benzomorpholine derivatives is described, in which an o-nitrophenoxy carbonyl compound is hydrogenated in the presence of extraneous metal-doped sponge metal catalysts based on nickel or cobalt with ring formation.

  • Process for preparing acyl amide compounds
    Patent number: 8222408
    Abstract: A process for preparing acyl amide compounds is described, in which a recrystallized o-nitrophenoxy carbonyl compound is hydrogenated with hydrogen gas in the presence of a nickel sponge metal catalyst with ring closure to form a benzoxazine, which is then reacted with an acyl halide to give the corresponding acyl amide compound.
