A short and efficient total synthesis of the bromotyrosine-derived alkaloid psammaplysene A

Xu, Jingjing,Wang, Kai,Wu, Jinlong

, p. 13747 - 13749 (2018/04/25)

Psammaplysene A, an inhibitor of FOXO1a-mediated nuclear export, has been synthesized by a concise and improved route from tyrosine-derived acid and amine fragments which were easily constructed using commercially available p-hydroxybenzaldehyde and tyramine as starting material, respectively. The strategy provides an efficient access of psammaplysene analogues that can be explored for potential pharmaceutical or biological activities.
