Total synthesis of (-)-panduratin D

Chem Commun (Camb). 2022 Jul 28;58(61):8564-8567. doi: 10.1039/d2cc02980d.

Abstract

Herein, an enantioselective total synthesis of (-)-panduratin D, a novel secondary metabolite against human pancreatic PANC-1 cancer cell, from commercially available 3-methoxyphenol is reported. The synthesis was completed in nine steps and the key features include Sonogashira coupling, anionic Snieckus-Fries rearrangement, directed ortho metalation, tandem Si → C Alkyl rearrangement/Claisen-Schmidt condensation, and chiral boron complex-promoted asymmetric Diels-Alder cycloaddition. These endeavors could facilitate the biological studies of (-)-panduratin D and its analogs.
