The NMR spectra of α-cyano-β-amino-β-alkylacrylic esters prepared from α-cyano-β-methoxy-β-alkylacrylic esters and simple amines have been studied. It has been found that these aminoesters, in a variety of solvents, are all present in an intramolecular hydrogen-bonded enamine form with a chelate ring.
研究了由α-氰基-β-甲氧基-β-烷基丙烯酸酯和简单胺制备的α-氰基-β-氨基-β-烷基丙烯酸酯的核磁共振谱。已经发现,这些氨基酯在各种溶剂中都以具有螯合环的分子内氢键合烯胺形式存在。
