Debutenoyl-aspertetronin A was synthesized from γ-valerolactone-γ-carboxylic acid (4) via 2,5-dihydro-3-hydroxy-2-methyl-5-oxo-2-furanpropanoic acid.Starting from (-)-(S)-4, (+)-(S)-5-hexyl-4-hydroxy-5-methyl-2(5H)-furanone (19) was synthesized, and by comparison of its optical rotation with that of an authentic sample it was proved that aspertetronin A had (R) configuration, and gregatin A had (S) configuration at their respective chiral carbon.
