1′,2′-Dideacetylboronolide, an α-pyrone from Iboza riparia

Abstract

The structural elucidation of 1′,2′-dideacetylboronolide, 5,6-dihydro-6-(3′-acetoxy-1′,2′-dihydroxyheptyl)2-pyrone, a new α-pyrone isolated from the leaves of Iboza riparia has been performed. Additionally, three sterols, sitosterol, stigmasterol and campesterol, have been identified in this species.
