摘要：

A new furanopyrone derivative, (-)-etharvensin (1), was isolated from the stem bark of Goniothalamus arvensis. Semisynthesis of the 7-ethoxyfuranopyrone 1 was achieved by addition of EtOH in concentrated acid medium to the unsaturated alpha-pyrone (+)-altholactone (2). This protocol constitutes a novel, direct (single-step), and efficient method to prepare this class of bioactive compounds.
