Title: DMT via enamine reaction, possible...?
Post by: pHarmacist on October 07, 2002, 07:43:00 AM
This is a result of my wild imagination rather than something serious, but could it work?

Title: Good work

The Stork enamine alkylation is a good idea, however I don't see how you can easily go from the ketone to the indole ring.  Probably you need to reduce it first and then subject the alcohol to a beta-elimination.

The synthesis is a bit elaborate, but I don't see why the hell it shouldn't be possible.  It looks OK, mechanistically speaking.

Glad to see you like retrosynthesis (it rules).  Now, the following step would be: look up the reactions in the chemical literature to obtain lab procedures.  If the yield are OK, your synthetic scheme would be great.

Keep up the good work  :) .
Title: Nice idea. The last reaction can be accomplished .

Nice idea. The last reaction can be accomplished with LiAlH4. But there might be a few problems:

- The first compound is not a ketone, it's an amide (or better: an anilide), so the first reaction might not work as expected.

- The second compound is not an enamine and will probably not react like one, it's an amino substituted aromatic ring similar to aniline.

- The product of the alkylation reaction will probably aromatize immediately, leaving you with a 2-pyrrolidyl-tryptamine.

Damned, I 'm a bit ashamed here ... I completely overlooked the amide (stupid me ...).  Yup, amides definitely don't react like ketones (resonance) ... so it won't work ...  :(

Lilienthal: Of course, i didn't give it much thought, not at much all, it seemed ok then, but of course indolic nitrogen has a free e-par ... something I often miss when it comes to indolum :).. well I guess I'll have to dust myself off and try agin.. my bad thank you for remarks guys.. :(
