3,4-Dimethoxyphenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine.
Chemistry[edit]
One of the earliest syntheses of DMPEA (then referred to as "homoveratrylamine") was that of Pictet and Finkelstein, who made it in a multi-step sequence starting from vanillin.[1] A similar sequence was subsequently reported by Buck and Perkin,[2] as follows:
- 3,4-Dimethoxybenzaldehyde (veratraldehyde) → 3,4-Dimethoxycinnamic acid → 3,4-Dimethoxyphenylpropionic acid → 3,4-Dimethoxyphenylpropionamide → 3,4-Dimethoxyphenethylamine
A much shorter synthesis is given by Shulgin and Shulgin:[3][4]
Derivatives[edit]
A known use was in the synthesis of Bevantolol.
Pharmacology[edit]
DMPEA has some activity as a monoamine oxidase inhibitor.[5]
Occurrence[edit]
DMPEA occurs naturally along with mescaline in various species of cacti such as San Pedro and Peruvian Torch.[6][7][8]
