Antimicrobial bioassay-guided fractionation of <i>Microcera larvarum</i> led to the isolation of a γ-lactone with a furo[3,4-<i>b</i>]pyran-5-one bicyclic ring system (<b>1</b>) and three known compounds, (3<i>S</i>,4<i>R</i>)-4-hydroxymellein (<b>2</b>), (3<i>S</i>,4<i>S</i>)-4-hydroxymellein (<b>3</b>) and 7-hydroxy-3-(1-hydroxyethyl)isobenzofuran-1(3<i>H</i>)-one (<b>4</b>). Structure elucidation was conducted by NMR spectroscopic methods. Absolute configuration of <b>1</b> (2<i>R</i>, 3<i>S< ...[more]
