Abstract:
The five-membered oxacyclic system of furan-2(5H)-ones, commonly named as γ- butenolides or appropriately as Δα,β-butenolides, is of high interest since many studies have proven its bioactivity. During the past few years, Δα,β-butenolides have been important synthetic targets, with several reports of new procedures for their construction. A short compendium of the main different synthetic methodologies focused on the Δα,β-butenolide ring formation, along with selected examples of compounds with relevant biological activities of these promising pharmaceutical entities is presented.

Abstract:
To investigate structurally novel and anti-neuroinflammatory natural compounds from marine-derived microorganisms, the secondary metabolites of Aspergillus terreus Y10, a fungus separated from the sediment of the coast in the South China Sea, were studied. Three new compounds (2–4), with novel open-ring butenolide skeletons, were isolated from the ethyl acetate extract of the culture medium. In addition, a typical new butenolide, asperteretal F (1), was found to dose-dependently inhibit tumor necrosis factor (TNF-α) generation with an IC50 of 7.6 μg/mL.

Abstract:
Condensation of 2-butenolide with 5-(4-X-phenyl)-2-furaldehydes (X = H, CH3, OCH3, Br, Cl, NO2) in methanol in the presence of piperidine as catalyst afforded the corresponding 4-[5-(4-X-phenyl-2-furfurylidene)]-2-butenolides. As shown by 1H NMR spectra, the reaction afforded mixtures of Z- and E-isomers which on crystallization were isomerized to the stable Z-isomers (except when X = NO2). 4-Bromo-2-butenolide reacted with sodium salts of 2-mercaptobenzoxazole and 2-mercaptobenzimidazole to give the corresponding 4-(benzazoyl-2-thio)-2-butenolides, probably by an anion-radical mechanism.

Twelve analogs of the strigol D-ring (butenolides) were evaluated at 0.1 mM as germination regulators of 26 weed and crop seeds.

The response rate for dicots was greater but still primarily inhibitory. Dormant lettuce seeds (both light-sensitive and light-insensitive), Palmer amaranth, and redroot pigweed showed several significant responses, both inhibitory and stimulatory. Some of the bu

Interesting antifungal activities against the filamentous strain Absidia corymbifera, and cytostatic activities against leukemic cells HL-60 and CCRF-CEM were found. The cytostatic activity requires the presence of both the butenolide ring and the alkylsulfanyl group bound to tetrazole ring. In addition, the feasibility of Pd-c

Chiral 1,3-dioxolans were prepared in high yields (80-96%) by the exchange reaction of diisopropyl L-tartrate with triethyl orthoformate, triethyl orthoacetate and triethyl orthobenzoate. These were reacted with 2-trimethylsilyoxyfuran (TMSOF) under Lewis acid conditions to give optically active butenolides. The stereoselectivity and yield were not very good.
