  In this research the reaction between alkyl(aryl) isocyanides, dibenzoylacetylene, ninhydrin and ammonium acetate leads to production of highly functionalized inminofuranes. A dynamic NMR effect is observed in the 1H NMR spectra of these compounds as a result of restricted rotation around the single bond linking the indole moiety and the furan system. The free-energy of activation (ΔG#) for this process is 75-83 kJ mol-1. تفاصيل المقالة
