Eighteen substituted 2-phenyl-5,5-dialkylimidazolinones 2 have been prepared by cyclizations of substituted 2-(N-benzoylamino)alkanamides 1. The cyclization of methylamides 1 proceeds at room temperature whereas primary amides are cyclized on boiling. The 1H and 13C nmr spectra of the imidazolinones are presented and the changes in their spectra connected with their protonation in hexadeuteriodimethyl
通过取代的2-(N-苯甲酰基氨基)烷基酰胺1的环化反应已经制备了十八个取代的2-苯基-5,5-二烷基咪唑啉酮2。甲基酰胺1的环化反应在室温下进行,而伯酰胺在沸腾时被环化。给出了咪唑啉酮的1 H和13 C nmr光谱,并讨论了在六氘代二甲基亚砜-三氟乙酸混合物中其光谱与质子化有关的变化。
