Title: Some patents...
Post by: Epikur on February 29, 2000, 07:08:00 PM

In the course of my quest for novel recreational drugs I came across some patents which might be of interest for those involved in the exploration of more traditional compounds:

Patent US2802865 (http://l2.espacenet.com/dips/viewer?PN=US2802865&CY=gb&LG=en&DB=EPD)

Teaches the preparation of methcathinone (alpha-methylaminopropiophenone) by oxidizing ephedrine with sodium dichromate in H2SO4/water.

Patent US3282959 (http://l2.espacenet.com/dips/viewer?PN=US3282959&CY=gb&LG=en&DB=EPD)

7-Chloro-alpha-Methyltryptamine Derivatives
Might be interesting for the friends of tryptamines.

Patent EP648744 (http://l2.espacenet.com/dips/viewer?PN=EP648744&CY=gb&LG=en&DB=EPD)

Teaches an interesting way to split off an alpha-OH from a phenylalkylalkohol, using a borane dimethylsulfide complex. (Example 6, page 17)

Have to have what? All the patents linked above are in PDF format already. And if you use GetIDPL to download patents they are automatically stitched together to form a multi-page file.
