Biomimetic synthesis of Tramadol†
Abstract
Tramadol has recently been isolated from the roots and bark of Nauclea latifolia. A plausible biosynthetic pathway has been proposed and the product–precursor relationship has been probed by 13C position-specific isotope analysis. By further exploring this pathway, we demonstrate that a key step of the proposed pathway can be achieved using mild conditions that mimic in vivo catalysis.
