(−)-Thebaine [PDF]

Acta Crystallographica Section C Crystal Structure Communications, 1996
The structure of the opioid thebaine, 6,7,8,14-tetradehydro-4,5-epoxy-3,6-dimethoxy-17-methylmorphinan, C19H21NO3, has been determined by single-crystal X-ray diffraction techniques at low temperature.

Precursors of the mammalian synthesis of morphine: (+)-salutaridine and (−)-thebaine from (+)-6-demethylsalutaridine, and (−)-N -13 CH3 -thebaine from (−)-northebaine

FEBS Letters, 1986
Standard samples of pure (+)-salutaridine and (−)-thebaine required to study the mammalian origin of morphine, were prepared from (+)-6-demethylsalutaridine by published procedures and were characterized by CD spectra and physical data.

Dearomative Access to (−)-Thebaine and Derivatives

Organic Letters, 2023
A synthesis of the natural product thebaine is reported in eight steps from commercially available starting materials, hinging on the dearomatization and coupling of simple aromatic starting materials. This provides divergent access to two unnatural opioid derivatives and is aimed at the long-term development of synthetic opioid analogs of the ...
