The synthesis of N-substituted β-(5-amino-2-furyl) nitroolefins
Studying nucleophilic substitution reactions in a number of β-(5-halo-2-furyl) nitroolefins (I) with secondary amines, we have shown for the first time the possibility of synthesizing the previously unknown N-substituted β-(5-aminofuryl)nitroolefins (II). We have found that the smoothest substitution reaction takes place in the case of the 5-halo-furylnitropropenes (I, R=CH3) with morpholine and methylaniline when their alcoholic solutions are heated.
