Synthesis of a Novel Bicyclic Scaffold Inspired by the Antifungal Natural Product Sordarin

Authors

Abstract

A simplified bicyclic scaffold inspired by the antifungal natural product sordarin was designed and synthesized which maintains the carboxylic acid/aldehyde (or nitrile) pharmacophore. A densely functionalized chiral cyclopentadiene was constructed in 8 steps and utilized in a Diels-Alder reaction with acrylonitrile. The resulting [2.2.1]cycloheptene was transformed into a scaffold possessing vicinal carboxylic acid and nitrile groups, with orientations predicted to provide high affinity for the fungal protein eukaryotic elongation factor 2 (eEF2).
