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.
