A new method combining yeast fermentation and enzymes produces the recreational drug MDMA (Ecstasy) and related compounds, offering an alternative to chemical synthesis. The process starts with a yeast-based system that converts ring-substituted benzaldehyde precursors into phenylacetylcarbinol derivatives using variants of pyruvate decarboxylase. Among seven wildtype enzymes tested, Candida tropicalis PDC gave the highest yield from piperonal, and a mutant further improved production. Five of sixteen tested benzaldehyde analogs yielded corresponding derivatives with 20–70% efficiency, allowing purification of milligram quantities. A stereoselective transaminase then converted all five derivatives, followed by N-methylation and chemical reduction to produce MDMA and its analog 6-chloro-MDMA. This is the first reported bioproduction method for MDMA and other methamphetamine derivatives.
