Model reactions and natural occurrence of furans from hypersaline environments [PDF]
Biogeosciences, 2014 Volatile organic compounds like furan and its derivatives are important for atmospheric properties and reactions. In this work the known abiotic formation of furan from catechol under Fenton-like conditions with Fe3+ sulfate was revised

Gold(I)-catalyzed formation of furans by a Claisen-type rearrangement of ynenyl allyl ethers
Beilstein Journal of Organic Chemistry, 2011 A series of ynenyl allyl ethers were rearranged into polysubstituted furans in the presence of a gold(I) catalyst. It is proposed that the transformation involves a Claisen-type rearrangement that allows the efficient creation of quaternary centers under

Tunable Oleo-Furan Surfactants by Acylation of Renewable Furans
ACS Central Science, 2016 An important advance in fluid surface control was the amphiphilic surfactant composed of coupled molecular structures (i.e., hydrophilic and hydrophobic) to reduce surface tension between two distinct fluid phases. However, implementation of simple surfactants has been hindered by the broad range of applications in water containing alkaline earth ...
