Catalytic hydrogenation of kaurenoic and grandiflorenic acids methyl esters with RuCl2(DMSO)4 in homogeneous and biphasic media.

Abstract

RuCl2(DMSO)4 was used in hydrogenation reactions of kaurenoic and grandifl orenic acid methyl ester in homogeneous medium and grandifl orenic acid methyl ester in biphasic toluene/water media. The reaction products were characterized by GC-MS. The catalytic parameters were optimized giving high percent conversion and some stereomeric preference for both acids.
