Organocatalytic Enantioselective Approach to Spirocyclic Δβ,γ-Butenolides [PDF]
, 2014 A novel method for the preparation of the spirocyclic Δβ,γ-butenolides is presented. The developed strategy is based on a trienamine-mediated [4+2]-cycloaddition between (E)-3-alkylidene- 5-arylfuran-2(3H)-ones and 2,4-dienals. Target products containing

Neuroprotective furanones from a soil-derived fungus Penicillium paxilli ga254
Journal of Asian Natural Products ResearchThree furanone derivatives (1–3), including one new compound, penicifuranone A (1), and one new natural product (2), along with one known dihydropyranone (4) were isolated from the solid rice medium fermentation of Penicillium paxilli ga254. The structures of these compounds were elucidated using comprehensive NMR spectroscopic analysis.
