We designed and synthesized a series of derivatives containing the right-side DFGH-ring structure of physalin-type natural products, decorated with a hydrophobic substituent. The synthetic scheme utilizes a highly efficient, one-pot protocol for simultaneous construction of the GH-ring system, promoted by HF/pyridine. Among the compounds synthesized, 5d inhibited TNF-α-stimulated NF-κB activation with similar potency to physalin B.
