Chemistry:Pseudotropine

From HandWiki

Pseudotropine (3β-tropanol, ψ-tropine, 3-pseudotropanol, or PTO) is a derivative of tropane and an isomer of tropine. Pseudotropine can be found in the Coca plant along with several other alkaloids [1]

Synthesis

In the laboratory it is made by the reduction of tropinone:[2] According to the article, a good stereoselectivity of pseudotropine over endotropine could be achieved when employing a Meerwein–Ponndorf–Verley reduction or sodium metal in n-pentanol.

Derivatives

  • Pudafensine
  • Tropigline (Tigloidine, ticloidine) [533-08-4] (E)-form Produced by Physalis peruviana. Anticholinergic, anti parkinsonian drug.[3][4][5]
  • Convolamine
  • Valtropine
  • Pseudotropine benzoate (tropacocaine)
