摘要
We recently reported a new class of triphenylphosphine and isocyanide based multicomponent reactions (Ph3P/DAAD and IMCRs/DAAD) mediated by R3P/DAAD and RNC/DAAD zwitter-ionic intermediates in the presence of CH, OH, and NH acids. Herein. the reactions of Huisgen 1:1 zwitterionic intermediates, generated from diallyl acetylenedicarboxylates (DAAD), trivalent phosphorus reagents, and isocyanides, with aromatic carboxylic acids as initial proton source are investigated. This novel binucleophilic (R3P-RNC/DAAD) system afforded 2-aminofuran derivatives.
