Cytat:QUALITATIVE COMMENTS: (with 14 mg) “I was well aware of things at the end of two hours, and I was totally unwilling to drive, or even go out of the house. I was reminded continuously of  2C-B with its erotic push, and the benign interplay of colors and other visual effects. But it is so much longer lived. I am a full +++, very stoned, and there is no believable sign of dropping for another several hours. There is a good appetite (again, 2C-B like), and I managed to sleep for a few hours, and all the next day I was spacey and probably still a plus one. The day yet following, I was finally at a believable baseline. Both of these days were filled with what might be called micro doze-offs, almost like narcolepsy. Maybe I am just sleep deprived.”

(with 16 mg) “The first effects were felt within one hour, and full effects between 2 1/2 and 3 hours. Tremendous clarity of thought, cosmic but grounded, as it were. This is not at all like  LSD , and is a lot mellower than the  2C-T family. For the next few hours it was delightful and fun and I felt safe and good-humored. I got to sleep without much difficulty while still at a plus three, and my dreams were positive and balanced, but I awoke irritable and emotionally flattened. I did not want to interact with anyone. The first 16 hours of this stuff were great, and the second 16 hours were a bit of a drag. Just twice as long as it ought to be.”

(with 16 mg) “I was at full sparkle within three hours, and I continued to sparkle for the longest time. The tiredness that comes after a while probably reflects the inadequacy of sleep. I was aware of something still going on some two days later.”

EXTENSIONS AND COMMENTARY: In the eventual potency assessment of a drug, there must be some consideration of not only the dosage needed, but the duration of effects. The area under the curve, so to speak. By these measures, this phenethylamine is a record breaker, in that it is not only amongst the most potent, but it goes on and on and on.

There are a couple of chemical commentaries. One, the miserable phenol-to-ether-to-aldehyde series of steps, so maddeningly unsatisfactory in the  2C-G-4 process, was completely comfortable here. The reactions rolled, and the yields were most satisfactory. Secondly, this is one of the few phenethylamines that is a racemate. The strange geometry of the norbornane ring carries within it a chiral character, so this compound is potentially resolvable into two optically active forms. That might be quite a task, but it would have the value of providing for the first time a pair of isomers that were asymmetric in the 3,4-aliphatic part of the molecule. To the extent that some insight into the geometry of the receptor site can be gleaned from the absolute configurations of active agonists, here is a compound where the subtle variations are over there at the ring substitution area of the structure, rather than at the well-explored alpha-carbon atom. Some day I might try to resolve this drug into its optical isomers. But I suspect that it might be quite difficult.

A number of chemical variations of 2C-G-5 are obvious. The dihydroxybenzonorbornane compound that was the starting point of all this was certainly the adduct of cyclopentadiene and benzoquinone, with the double bond reduced. The same chemistry with 1,3-cyclohexadiene would give a two-carbon bridge instead of the one-carbon bridge of norbornane and, after hydrogenation, would provide a non-chiral analog with two ethylene bridges between the 3- and 4-position carbons. This is a cyclohexane ring connected, by its 1- and 4-positions, to the two methyl groups of 2C-G . With six carbons in this aliphatic mess, the compound is probably best called  2C-G-6 . It should be easily made, and it is certain to be very potent. And there are potentially several other Diels Alder dienes that might serve with benzoquinone as the dieneophile. There are aliphatic things such as hexa-2,4-diene and 2,3-dimethylbutadiene. The textbooks are filled with dozens of diene candidates, and benzquinone will always provide the two oxygens needed for the eventual 2,5-dimethoxy groups of the phenethylamine.
