A new chlorotryptamine alkaloid, N ‐chloromethyl‐ N , N ‐dimethyltryptamine, was isolated from a methanol extract of the Chinese shrub Acacia confusa Merr., together with its known hallucinogenic analogues, N ‐methyltryptamine, N , N ‐dimethyltryptamine and N , N ‐dimethyltryptamine‐ N ‐oxide. The new compound was an artefact of the isolation conditions. The complete 1 H and 13 C NMR assignments for these compounds were carried out using 1 H, 13 C, DEPT, gCOSY, gHSQC and gHMBC NMR experiments. Copyright © 2007 John Wiley & Sons, Ltd.
