TL;DR

The formation and decomposition of aminals is addressed in light of epidemiological evidence linking them to a recent outbreak of EMS.

Abstract

The condensation of tryptophan and acetaldehyde affords a bisindolylaminal of tryptophan which is indistinguishable from contaminant “97.” The formation and decomposition of aminals is addressed in light of epidemiological evidence linking them to a recent outbreak of EMS.
