Coupling the peptide part with lysergic acid afforded 1.

But for some reason, Hoffman could not forget the relatively uninteresting LSD-25. In  he says:

Coupling the peptide part with lysergic acid afforded 1.

In the late 1930s, Albert Hoffman was working in the pharmacological department of Sandoz, in Basel, Switzerland. He was studying derivatives of lysergic acid, including systematically reacting the acid group with various reagents, to produce the corresponding amides, anhydrides, esters, . One of these derivatives was the , made by addition of the -N(C2H5)2 group, and it was named LSD-25. But the new substance didn't appear to have any particularly useful medical properties, although the research report noted, in passing, that "". For the next five years, nothing more was heard of the substance LSD-25.

Having synthetic (+)-7 in hand, we can claim the total synthesis of all the alkaloids which were prepared earlier from (+)-7 that had been obtained through degradation of natural lysergic acid.AB - The first direct synthesis of (+)-lysergic acid (2a) suitable for scale-up has been achieved by the following reaction sequence.

Being passed making acid diethylamide, abbreviated lsd.


Hofmann's discovery of the effect of LSD in Basel came 5 years after his original synthesis of the molecule in 1938. LSD-25, as it was called then, was synthesized and tried on animals. No interesting effects appeared, and the molecule was consigned to the "useless" heap. If it had stayed there, the state of today's world would be different.

A NEW SYNTHESIS OF (±)-LYSERGIC ACID

Because of its hallucinatory properties, LSD was widely adopted by the hippy culture of the 1960's, who claimed it led to higher states of consciousness and helped them search for religious enlightenment. ' even wrote a song ('Lucy in the Sky with Diamonds') which allegedly describes the psychedelic effects of LSD.

The nature and the course of this extraordinary disturbance raised my suspicions that some exogenic intoxication may have been involved and that the Iysergic acid diethylamide with which I had been working that afternoon could have been responsible. I had separated the two isomeric forms that are formed by this synthesis, namely Iysergic diethylamide and isolysergic acid diethylamide and prepared the crystalline water soluble salt of Iysergic acid diethylamide with tartaric acid. However, I could not imagine how this compound could have accidentally found its way into my body in a sufficient quantity to produce such phenomena. Moreover, the nature of the symptoms did not tally with those previously associated with ergot poisoning. In order to get to the root of the matter, I decided to conduct some experiments on myself with the substance in question. I started with the lowest dose that might be expected to have any effect, i.e., 0.25 mg LSD. The notes in my laboratory journal read as follows:

By the time the doctor arrived, the peak of the crisis had already passed. As far as I remember, the following were the most outstanding symptoms: vertigo, visual disturbances; the faces of those around me appeared as grotesque, colored masks; marked motoric unrest, alternating with paralysis; an intermittent heavy feeling in the head, limbs and the entire body, as if they were filled with lead; dry, constricted sensation in the throat; feeling of choking; clear recognition of my condition, in which state I sometimes observed, in the manner of an independent, neutral observer, that I shouted half insanely or babbled incoherent words. Occasionally I felt as if I were out of my body.
The doctor found a rather weak pulse but an otherwise normal circulation.... Six hours after ingestion of the LSD my condition had already improved considerably. Only the visual disturbances were still pronounced. Everything seemed to sway and the proportions were distorted like the reflections in the surface of moving water. Moreover, all objects appeared in unpleasant, constantly changing colors, the predominant shades being sickly green and blue. When I closed my eyes, an unending series of colorful, very realistic and fantastic images surged in upon me. A remarkable feature was the manner in which all acoustic perceptions (e.g., the noise of a passing car) were transformed into optical effects, every sound evoking a corresponding colored hallucination constantly changing in shape and color like pictures in a kaleidoscope. At about one o'clock I fell asleep and awoke next morning feeling perfectly well.
