Synthesis of a deuterium‐labelled standard of bufotenine (5‐HO‐DMT)

Journal of Labelled Compounds and Radiopharmaceuticals October 1, 2007 Yu Yun Wang, Chinpiao Chen 6 citations

Abstract The Batcho–Leimgruber strategy was employed to synthesize 3‐(2‐dimethylamino‐[ 2 H 4 ]‐ethyl)‐1 H ‐indol‐5‐ol (bufotenine, 5‐HO‐DMT) ( 8 ) from commercial 3‐methyl‐4‐nitro‐phenol ( 1 ), benzyl bromide and N,N –dimethylformamide–dimethylacetal. Compound 4 was synthesized from compound 3 using the Batcho–Leimgruber strategy in the presence of Raney nickel and hydrazine hydrate. Compound...

Synthesis of deuterium‐labelled standards of (±)‐DOM and (±)‐MMDA

Journal of Labelled Compounds and Radiopharmaceuticals June 1, 2007 Ajam C. Shaikh, Yu Yun Wang, Chinpiao Chen 9 citations

AbstractThis study describes the synthesis of deuterium‐labelled (±)‐4‐methyl‐2,5‐dimethoxyamphetamine (DOM) and (±)‐1‐(7‐methoxy‐1,3‐benzodioxol‐5‐yl)propan‐2‐amine (MMDA). The isotopically labelled compounds are potentially used as internal standards in gas chromatography–mass spectrometry (GC–MS) assays. Copyright © 2007 John Wiley & Sons, Ltd.

Synthesis of deuterium labeled standards of 5‐methoxy‐N,N‐dimethyltryptamine (5‐Meo‐DMT)

Journal of Labelled Compounds and Radiopharmaceuticals August 14, 2006 Ya-Zhu Xu, Chinpiao Chen 14 citations

Abstract The Batcho‐Leimgruber strategy was employed to synthesize 5‐[ 2 H 3 ]‐methoxy‐1 H ‐indole 4 from commercially available 5‐hydroxy‐2‐nitrotoluene 1 and CD 3 I. Compound 4 was treated with oxalyl chloride, dimethylamine and lithium aluminum hydride to yield 5‐[ 2 H 3 ]‐methoxy‐ N , N ‐dimethyltryptamine 6 . Copyright © 2006 John Wiley & Sons, Ltd.
