Glochidiolide, Isoglochidiolide, Acuminaminoside, and Glochidacuminosides A—D from the Leaves of Glochidion acuminatum MUELL.

Abstract

The dimeric butenolides glochidiolide and isoglochidiolide, a new glucoside of a nitrogen-containing C₈ dimer, acuminaminoside, and glucosides of C₈ compounds, designated glochidacuminosides A—D, were isolated from the leaves of Glochidion acuminatum. The structures of glochidionolactone and acuminaminoside were determined by X-ray analyses, and those of the remaining C₈ glucosides by NMR spectroscopic analyses, chemical conversion, and a modified Mosher's method.
