Synthetic efforts toward the eastern hemisphere of theonellamide C
… by Boger and co-workers, utilizing a key Sharpless aminohydroxylation reaction. The eHyAsn building block, Boc-eHyAsn(OTBS)-OH, was coupled with HCl.Phe.OMe using EDC/HOBt/NEt3/THF to afford Boc-eHyAsn(OTBS)-Phe-OMe in 68% yield. Our two early approaches toward the …
