An Interrupted Vinylogous Iso-Nazarov Reaction: Cycloisomerization of Conjugated Trienones to Cyclopenta[b]furan Derivatives
(American Chemical Society, 2014-05)
Iron(III) chloride-catalyzed cyclopentannulation of π-conjugated 1,3-dicarbonyl compounds is described. An interrupted vinylogous iso-Nazarov reaction of trienones was established in which cyclopenta[b]furan derivatives ...
Synthesis and characterization of furan resin and their nanocomposites
(Wiley, 2010-08)
Formaldehyde emissions are nowadays trying to be reduced because of its atmospheric pollutant character. Besides, it is encouraged the use of polymeric materials synthesized from biomass wastes as row materials. For this ...
Furan resins as replacement of phenolic protective coatings: Structural, mechanical and functional characterization
(Elsevier, 2013-10-27)
Phenolic coatings are usually a convenient and economical way to protect metallic materials against wear and corrosion. Furan resins are analogous to phenolics, as they are obtained by replacing formaldehyde by furfural ...
Synthesis of Diiodo-Functionalized Benzo[b] furans via Electrophilic Iodocyclization
(Soc Brasileira Quimica, 2017)
An electrophilic iodocyclization reaction involving alkynylated 2-iodoanisoles and molecular iodine in the presence of sodium bicarbonate was developed and diiodo-functionalized benzo[b] furans were obtained in yields from ...
Effect of carob variety and roasting on the antioxidant capacity, and the phenolic and furanic contents of carob liquors
BACKGROUND The production of the traditional carob liquor from Algarve (Portugal) depends on numerous factors such as carob processing, variety and maceration conditions. An experimental design with 36 runs was created to ...
Curing kinetics of a furan resin and its nanocomposites
(Elsevier Science, 2011-03)
A furan resin was synthesized from furfural and phenol and it was expected to have similar properties to the commonly used phenolic resins because the former was obtained by the replacement of formaldehyde by furfural, ...
Asymmetric Hydrogenation of Furan- containing Ketones over Tartaric Acid-modified Raney Nickel Catalyst
(Pergamon-Elsevier Science Ltd, 2004-12)
The hydrogenation of b-keto esters containing a furan unit at the conjugated position to the b-carbonyl group was carried out over a chiral heterogeneous catalyst, tartaric acid-modified Raney nickel. The hydrogenation ...
