Summary
The study describes an efficient method for synthesizing bis-catechol-thioether metabolites of MDMA (ecstasy) with high purity (99%) using a one-pot electrochemical process. This method is environmentally friendly and offers advantages in terms of atom economy and reduced waste. The potential neurotoxic effects of these metabolites on rat hippocampal neurons, including necrosis and apoptosis, are also discussed.

Abstract
A straightforward one-pot electrochemical synthesis of bis-catechol-thioether metabolites of MDMA (ecstasy), 2,5-bis(glutathion-S-yl)-N-methyl-α-methyldopamine and 2,5-bis(N-acetylcystein-S-yl)-N-methyl-α-methyldopamine, in acceptable yields and high degree of purity (99%), is described under environmentally friendly conditions. The undeniable benefits of this method, which uses N-methyl-α-methyldopamine as the starting catechol, without the need to isolate the catechol-thioether mono-conjugate intermediate, include atom economy, as well as economies of time, resource management, and waste generation. Finally, the possible participation of the catechol-thioether bis-conjugates in the long-term neurotoxic effects of MDMA is discussed through their ability to elicit necrosis and apoptosis on rat hippocampal pyramidal neurons.
