Hydrogenation of stigmasterol

  • Published:
Lipids

Abstract

Hydrogenations of stigmasterol over 5% Pd/C, 5% Ru/C, Pt, Raney Ni, Raney Co, Ni/kieselguhr, and tris(triphenylphosphine)chlororhodium catalysts and with diimide generated from hydrazine andp-toluenesulfonylhydrazide were studied to determine the best conditons for the selective reduction of the Δ22 double bond. The best results (maximum stigmasterol reduction, minimum stigmastanol formation) were obtained with Raney nickel at room temperature and atmospheric pressure.
