New acetylenic nematicidal compound, penipratynolene (1), methy (2′R)-4-(2′-hydroxy-3′-butynoxy)benzoate, together with two known compounds, 6-methoxycarbonylpicolinic acid (2) and 2,6-pyridinedicarboxylic acid (3), were isolated from the culture filtrate of Penicillium bilaiae Chalabuda. The structures of 1–3 were established by spectroscopic methods. The absolute configuration of 1 was confirmed by using a modified version of Mosher’s method. Compounds 1–3 showed nematicidal activity of 77… Expand
