A novel and safe approach was developed for the synthesis of bioactive 2-aroyl-3,5-diarylfurans in excellent yields by using a cyanide-impregnated anion-exchange resin as a versatile reagent. The possibility of reusing the polymer-supported reagent makes the process environmentally friendly and economically advantageous. Georg Thieme Verlag Stuttgart. New York.

experimental part, p. 442 - 445 (2011/06/23)
The major product of the reaction of 2,4,6-triphenylpyranyl with (diacetoxy-λ3-iodanyl)benzene in acetonitrile and acetone was 2,4,6-triphenylpyrylium acetate. Analogous reaction in isopropyl alcohol resulted in the formation of methane, carbon dioxide, 1,3,5-triphenylpent-2-ene- 1,5-dione, 2-benzoyl-3,5-diphenylfuran, 1,3,5-triphenylpenta-2,4-dien-1-one, and a small amount of 2,4,6-triphenylpyrilium acetate.
New synthetic approach for the construction of multisubstituted 2-acyl furans by the IBX-mediated cascade oxidation/cyclization of cis-2-En-4-yn-1-ols (IBX = 2-iodoxybenzoic acid)

A new approach for the construction of multisubstituted 2-acyl furans through cis-2-En-4-yn-1-ols (IBX=2-iodoxybenzoic acid)-mediated oxidation/cyclization in dimethyl sulfoxidse (DMSO) was developed. The results show that the introduction of an alkyl group at Cl provided a satisfactory yield of furan of 60% at 90°C. It is seen that IBX act as an electrophile to promote the cycloaddition of carbonyl group to the alkyne moiety. The furan derivatives are found to be useful synthetic intermediates for access to the compounds bearing biological activity. The studies also elucidate this reaction mechanism and extend the scope of synthetic utility of multisubstituted 2-acyl furans.

A facile three step process, under mild conditions, for the synthesis of 2,4-diarylfurans with the same or different substituents on the two aryl rings, starting from benzaldehydes and acetophenones, employing Haller-Bauer type cleavage of 2-aroyl-3,5-diarylfurans is described.
The reaction of 1,3,5-triaryl-2-pentene-1,5-diones with bromine

, p. 261 - 264 (2007/10/03)
Bromination of 1,3,5-triaryl-2-pentene-1,5-diones results in the formation of a mixture of aryl-substituted 4-bromo-2-pentene-1,5-diones. In the presence of sodium acetate, this reaction affords 4-acetoxy-2-pentene-1,5-diones and products of intramolecula
