摘要：
A convenient procedure for the preparation of carbamate derivatives of 5-oxo-2,5-dihydrofuran (3) was described. The method is based on the Michael type addition of three alkyl carbamates (2) with 4-acetyl-5methyl-2,3-dihydro-2,3-furandione (1). According to H-1 nmr spectra of compounds show tautomeric forms (3,4,5) in CDCl3. In the solid state the synthesized compounds are enol forms (3). The products were characterized with molecular spectroscopic methods.
