Abstract
A stereoselective reduction of d‐lysergic acid amides to the 2,3‐dihydro derivatives is described. These new dihydro‐compounds can be dehydrogenated and oxidised with potassium nitroso‐disulphonate to form the corresponding 12‐hydrosy‐d‐lysergic acid amides besides the corresponding d‐lysergic acid amides.
