Solid-Support Based Total Synthesis and Stereochemical Correction of Brunsvicamide A
摘要:
A total synthesis of the cyanobacterial metabolite brunsvicamide A and the correction of its originally assigned stereochemistry are reported. Key elements were the construction of a urea building block, peptide elongation on solid phase, and on-resin cyclization of the peptide chain, with good overall yield. Detailed structural investigations uncovered that brunsvicamide A features a previously undetected D-lysine residue in its backbone, setting the foundation for all further investigations in this compound class.
The present application includes novel inhibitors of HCV, compositions containing such compounds, therapeutic methods that include the administration of such compounds.
