Abstract: carboxylic acid esterscarboxylic acid esters (acyclic compounds) P 0360 -078The Effect of Substituents of α-Alkyl Sidechains on Furan-Diazoester Interactions.-The reaction of various α-substituted furans with diazoesters (II) in the presence of a ruthenium catalyst followed by I 2 -induced isomerization is investigated. Thus, α-alkyl-substituted furans (I) undergo ring-opening to yield ketoesters (III)-(V). Under the same conditions, furfural (VI) and α-acetylfuran are affected at the sidechain, whereas aceta…
