3,4-Dimethoxyphenethylamine synthesis of Bevantolol. DMPEA has some activity as a monoamine oxidase inhibitor. DMPEA occurs naturally along with mescaline in various species of cacti such as San Pedro and Peruvian Torch. 3,4-Dimethoxyphenethylamine 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. 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
O-Acetylpsilocin Franz Troxler. Despite this, psilocetin remains a psychedelic compound with a limited history of use. It is theorized to be a prodrug for psilocin, as is psilocybin, which occurs naturally in most species of hallucinogenic mushrooms. This is because the aromatic acetyl moiety on the 4th position is subject to deacetylation by acidic conditions such as those found in the stomach. Psilocetin is "O"-acetylated psilocin, whereas psilocybin is "O"-phosphorylated. "O"-Acetylpsilocin can be obtained by acetylation of psilocin under alkaline or strongly acidic conditions. It is, therefore, a semi-synthetic compound. It is believed to be a prodrug of psilocin, however, speculation
