The stereo- and regiochemistry of di-, tri-, and tetracyclic enaminones upon catalytic hydrogenation on Pd and Pt catalysts seems to be mainly a function of the catalyst and the medium. The highest stereoselectivity was observed for multiflorine on Pd/C in which 99% of equatorial alcohol were formed in this case, the formation of alcohols proceeds via a ketonic intermediate. On platinum, irrespective
