      New tryptamine literature  Bookmark   

This new and forever growing thread is devoted to new literature relevant for tryptamine / lysergamide chemistry. Let's discuss these papers in separate threads for a better overview.

Heterocycles 51, 1131 1999 H. Sakagami, K. Ogasawara: A new synthesis of psilocin. A seven-step-low-over-all-yield-very-complicated synthesis.

J. Chem. Soc. Perk I 1045 2000 G. W. Gribble: Recent developments in indole ring synthesis - methodology and applications. Great review articel covering the whole modern indole chemistry. Someone (I forgot who) already mentioned this article at the old board.

What about the book 'LSD 25 and Tryptamine Syntheses' by O. Snow ? I didn't like his book on amphetamines much but the reference section was good.

The new Psilocin/Psilocybin/4-acetoxy-DMT synthesis by nichols is now available at my site (Thanks Omnipage 10, the only thing I had to correct was Et2O and CH2Cl2, which was interpreted as EzO and CHzCIz).
