“…3-Imino(hydrazono)-3H-furan-2-ones are convenient initial compounds for the creation of new derivatives of the aroyl-and pivaloylpyruvic acids (APA and PPA) [1,2], as well as new heterocyclic systems [3][4][5][6][7]. Preparation of 3-imino(hydrazono)-3H-furan-2ones can be carried out both from the already existing furan cycle [8][9][10][11][12][13][14], and methods of intramolecular cyclization of 2-imino(hydrazono)-4-oxobutanoic acids [15][16][17][18][19].…”

“…2-N 2 -Methylenesubstituted 4-aryl-2-hydrazino-4-oxobut-2-enoic and 5,5-dimethyl-2-hydrazino-4-oxohex-2-enoic acids cleanly underwent cyclization under the effect of acetic anhydride into 5-aryl-3-hydrazono-3H-furan-2-ones and 5-tertbutyl-3-hydrazono-3H-furan-2-ones.The analysis of published data shows that iminofuranones are available and convenient compounds for preparation of versatile acyclic and heterocyclic structures [2][3][4][5][6]. The application of iminofuranones in synthetic procedures requires an existence of a convenient method for their preparation with the possibility of substituents variation.…”

“…Chemical transformations of 3-hydrazinylidene-(imino)furan-2(3H)-ones afforded a variety of compounds [1][2][3][4][5][6][7][8][9][10], including those possessing biological activity [11][12][13][14][15]. Introduction of a pharmacophoric adamantyl fragment [16][17][18][19] into molecules of 3-hydrazinylidenefuran-2(3H)-ones extends the potential of these compounds as biologically active substances.…”
