Glycopentaphyllone: The first isolation of hydroperoxyquinolone from the fruits of Glycosmis pentaphylla
A new hydroperoxyquinolone alkaloid, glycopentaphyllone (1), along with nine compounds (2-10), was isolated from the fruits of Glycosmis pentaphylla. Their structures were elucidated on the basis of spectroscopic methods. The absolute configuration of glycopentaphyllone at C-2′ was established as S-...
