A large number of N,N-dialkylated tryptamines are known to induce psychoactive effects in humans. This has resulted in their increased attention within clinical and forensic communities. Deuterated tryptamines are ideal for use as internal standards during MS bioanalysis or of use in biochemical NMR studies. The present study reports on a microwave-enhanced synthesis of 22 N,N-dialkylated-[α,α,β,β-d4]-tryptamines via the reduction with lithium aluminium deuteride of glyoxalylamide precursors obtained by the procedure of Speeter and Anthony. Syntheses were carried out using a single-mode system under elevated pressure conditions where anhydrous tetrahydrofuran was used as the solvent at 150°C. Good yields were obtained within 5 min.

已知大量N,N-二烷基色胺对人类具有精神活性效应。这使得其在临床和法医领域受到越来越多的关注。氘代色胺非常适合用作MS生物分析过程中的内标,或在生物化学NMR研究中使用。本研究报告了一种通过锂铝氘化物还原甘油醛酰胺前体(Speeter和Anthony法获得)合成22种N,N-二烷基-[α,α,β,β-d4]-色胺的微波促进合成方法。合成在单模系统中进行,高温高压条件下使用无水四氢呋喃作为溶剂,温度为150°C。5分钟内即可获得良好的产率。版权所有 © 2008 John Wiley & Sons, Ltd.
