Norsampsones A–D, Four New Decarbonyl Polycyclic Polyprenylated Acylphloroglucinols from <i>Hypericum sampsonii</i>

Norsampsones A–D (<b>1</b>–<b>4</b>), four new decarbonyl polycyclic polyprenylated acylphloroglucinols, together with a new biogenetically related compound hypersampsone M (<b>5</b>), were isolated from the aerial parts of <i>Hypericum sampsonii</i>. Norsampsones A–D featured an unprecedented carbon skeleton with the loss of C-2 carbonyl in the phloroglucinol ring. All structures were determined by extensive NMR spectroscopic methods, ECD calculation, and single-crystal X-ray diffraction

Dioxasampsones A and B, Two Polycyclic Polyprenylated Acylphloroglucinols with Unusual Epoxy-Ring-Fused Skeleton from Hypericum sampsonii

Dioxasampsones A and B (<b>1</b> and <b>2</b>), two new polycyclic polyprenylated acylphloroglucinols with an unusual epoxy-ring-fused skeleton by new ways of cyclization, along with a new nor-PPAPs hypersampson R (<b>3</b>) with the loss of C-31–33 in isopentenyl, were isolated from the aerial parts of Hypericum sampsonii. <b>1</b> possessed an unexpected hexacyclic skeleton with a rare 2,7-dioxabicyclo[2.2.1]­heptane moiety, and <b>2</b> featured a unique tetrahydrofuro­[3,4-<i>b</i>]­furan-fused tricycle­[4.3.1.1^5,7]­undecane skeleton. The gross structures of the new compounds were determined by extensive NMR spectroscopic methods. Their absolute configurations were deduced by single-crystal X-ray diffraction and ECD calculations
