    SYNTHESIS AND CHARACTERIZATION OF N3-ACETYL DERIVATIVES OF SPIROHYDANTOINS
    (2022-01-01) Marinov M.; Frenkeva M.; Naydenova E.; Penchev P.; Stoyanov N.
    The following article describes the synthesis of N3-acetyl derivatives of spirohydantoins. The compounds are derived by applying the following technique: the Bucherer-Lieb method (α-series) and the Strecker method (β-series). The synthesized products are characterized by physicochemical parameters, elemental analysis, FTIR, 1H NMR, 13C NMR and 13C DEPT135 spectral data.
