In this study, we compared the enzymatic reduction of 10 drugs with a ketone group by homogeneous carbonyl reductase, aldehyde reductase and three dihydrodiol dehydrogenases of human liver cytosol. At least one and in some cases all of the three dihydrodi

As a continuation of our work, aimed at adopting the Mitsonobu reaction in the morphine series, a few representatives of dihydroisocodeines and dihydroisomorphines and their 14β-hydroxy analogues were prepared. p-Nitrobenzoic acid was used as carboxylic acid and the prepared esters were cleaved to obtain the title compounds. Using phthalimide as acidic component several new 6β-phthalimidodihydromorphine and dihydrocodeine derivatives and their 14β-hydroxy analogues have been synthesized. Cleavage of the phthalimido derivatives with hydrazine hydrate afforded the corresponding 6β-amino derivatives.

Process for the stereoselective synthesis of 6β-and 8β- hydroxy epimers by the chemical reduction of 6- and 8-keto derivatives in the morphine and morphinan series utilizing alkaline formamidinesulficic acid. The 6β- and 8β-hydroxy derivatives obtained according to the invention evidence narcotic antagonist and/or agonist activity and are also useful in the chemical and pharmacological standardization of various morphine and codeine derivatives and metabolites.
