One-pot, three-component reaction of isocyanides, dialkyl acetylenedicarboxylates, and non-cyclic anhydrides: synthesis of 2,5-diaminofuran derivatives and dialkyl (E)-2-[(N-acyl-N-alkylamino)carbonyl]-2-butenedioates
摘要:
Isocyanides, dialkyl acetylenedicarboxylates, and non-cyclic anhydrides, for example acetic anhydride or benzoic anhydride, react in one-pot to afford 2,5-diaminofuran derivatives and dialkyl (E)-2-[(N-acyl-N-alkylamino)carbonyl]-2-butenedioates in fairly good yields at room temperature.
Vinyltriphenylphosphonium Salt-Mediated Preparation of Fully Substituted Furans and Electron-Poor Imides from Benzoic acid, Cyclohexyl Isocyanide, and Acetylenic Esters
acetylenedicarboxylates by benzoic acid leads to vinyltriphenylphosphonium salts, which undergo complex reactions with cyclohexylisocyanide to produce corresponding densely functionalized furans and imides in fairly good yields in neutral conditions. The formulas of the products were deduced from their IR, 1H NMR, and 13C NMR spectra. The reaction is completely stereoselective.
