Synthesis and characterization of 5‐methoxy‐2‐methyl‐N,N‐dialkylated tryptamines

Drug Testing and Analysis January 1, 2012 Simon D. Brandt, Ruchanok Tearavarich, Nicola M. Dempster et al. 10 citations

Thirteen new tryptamine derivatives were synthesized and analyzed to provide reference data for forensic and clinical identification. Using NMR and mass spectrometry, the compounds were characterized and distinguished from each other and from related substances. Key mass spectral fragments were identified, including an iminium ion and indole-related ions at specific mass-to-charge ratios. The work extends earlier research on similar compounds and supplies analytical standards that can help professionals identify these substances before they cause adverse health effects.

Microwave‐accelerated preparation and analytical characterization of 5‐ethoxy‐N,N‐dialkyl‐[α,α,β,β‐H4]‐ and [α,α,β,β‐D4]‐tryptamines

Drug Testing and Analysis December 29, 2010 Ruchanok Tearavarich, Viwat Hahnvajanawong, Nicola M. Dempster et al. 10 citations

Twelve novel 5-ethoxy-N,N-dialkyl-tryptamines and their deuterated counterparts were synthesized using a microwave-accelerated reduction step that took 5 minutes in tetrahydrofuran at 150 °C. The resulting 24 tryptamines were characterized by nuclear magnetic resonance spectroscopy and gas chromatography ion trap mass spectrometry, revealing differential fragmentation of side-chain-related iminium ions. These compounds are intended as internal standards for bioanalytical and pharmacological assays, aiding identification of novel tryptamines from non-traditional sources, and are of immediate value in forensic, research, and public health contexts.
