Thomas, Alan F.,Damm, Hanne
, p. 505 - 506 (1986)
The conversion of alkyl-substituted 4-hydroxybut-2-ynones to 2,5-dialkyl-3-furanones via 2,5-dialkyl-methoxyfurans is described.
An Unusual Substitution Reaction in a Benzotetrazine Derivative
Almerico, A. M.,Boulton, A. J.
, p. 204 - 205 (1985)
1-Methyl-3H-pyrazolobenzotetrazin-3-one decomposes in alcohols, with loss of nitrogen and intramolecular hydrogen transfer, to form 5-alkoxymethyl-1,2-dihydro-1-phenyl-3H-pyrazol-3-ones.

Caine, Drury S.,Arant, Mark E.
, p. 2081 - 2086 (2007/10/03)
Heterocyclic ketones, such as 2,5-dimethyl-3(2H)-furanone, provide multifunctional intermediates to various compounds. One property of these that has proven useful is the ability to alkylate the γ′-position of the dienolate. This report demonstrates the versatility of γ′-dienolate substitutions as employed toward syntheses of certain natural products and highly reactive electrophiles provide the best substrates for efficient substitution.
New 5-(2-ethenylsubstituted)-3(2H)-furanones with in vitro antiproliferative activity
Chimichi, Stefano,Boccalini, Marco,Cosimelli, Barbara,Dall'Acqua, Francesco,Viola, Giampietro
, p. 5215 - 5223 (2007/10/03)
A convenient route to new 3(2H)-furanones is described through hydrogenolysis and subsequent acidic hydrolysis of isoxazoles. The antiproliferative activity of title compounds were evaluated against leukemia-, carcinoma-, neuroblastoma-, and sarcoma-derived human cell lines in comparison to the natural compound geiparvarin. The structure activity relationship indicated that the maximum in vitro antiproliferative activity correlates with the presence of a heterocyclic ring on the ethenyl moiety.
New Syntheses of Geiparvarin and 2,5-Dimethyl-3(2H)-furanone via CO2 Mediated Bond Reorganization
Inoue, Y.,Ohuchi, K.,Imaizumi, S.,Hagiwara, H.,Uda, H.
, p. 3063 - 3068 (2007/10/02)
A new synthesis of 3(2H)-furanones from 4-hydroxy-2-alkyn-1-one derivatives via CO2 mediated bond reorganization has been developed to the preparation of an antitumor agent, geiparvarin and a constituent of flavors, 2,5-dimethyl-3(2H)-furanone.
Silyl Nitronates in Organic Synthesis. Routes to Heterocycles and Cyclopentanoids. Synthesis of Allethrolone and Calythrone. Acylation and Cyanohydroxylation of Double Bonds. An Exploratory Study
Andersen, Soeren H.,Das, Nalin B.,Joergensen, Ruth D.,Kjeldsen, Gunhild,Knudsen, Jes S.,et al.
, p. 1 - 14 (2007/10/02)
Silyl nitronates are versatile reagents for the preparation of heterocycles by dipolar addition to double bonds.The intermediate isoxazolidines can be transformed to 2-isoxazolines, isoxazoles, furans, dihydrofuranones, pyrazoles, pyridazines and pyridazones.Reduction of 2-isoxazolines with Ti3+ leads to hydroxylated 1,4-diketones, which subsequently can be cyclized to cyclopentenones.Routes to calythrone, rethrolones, prostanoids and a number of naturally occurring dihydrofuranones are devised, as well as synthetic procedures for acylation, preparation of endiones, hydroxyacylation, cyanation and hydroxycyanation of double bonds.
Process for preparing 2,5-dimethyl-3-(2H)-furanone

, (2008/06/13)
There is disclosed a simple, economical process for preparing 2,5-dimethyl-3-(2H)-furanone by hydrolysis of the dimer of diacetyl at a temperature of 20°C to 120°C and in the presence of an acid, mineral or organic, or of a cationic resin, with elimination of a acetic acid.
