Abstract

Abstract X-Ray An X-ray analysis of two compounds isolated from Piper sanctum confirmed the trans configuration for 5-(methoxy) -cinnamyliden-4-methoxy-but-3-enolide (= piperolide [1]) and for 5-[trans-(2) -β-γ epoxy-α-methoxy-cinnamyliden]-4-methoxy-2 (5H) -furanon (= epoxypiperolide [2]). The stereochemistry of the semicyclic double bond is in favour of the Z-isomeres.
