and stereoselective procedure has been described for the synthesis of a series of β-enaminoesters and β-enaminones by vanadium(IV) acetylacetonate [VO(acac)2] catalyzed reaction of β-ketoesters and 1,3-diketones with both aliphatic and aromatic amines. X-ray crystallographic studies of some representative compounds corroborate two types of structural geometry formed by inter-molecular as well as intra-molecular
已经描述了一种有效的立体选择性方法,该方法可通过乙酰丙酮钒(IV)[VO(acac)2 ]催化β-酮酸酯和1,3-二酮与脂肪族化合物的合成来合成一系列β-烯胺酯和β-烯酮和芳香胺。一些代表性化合物的X射线晶体学研究证实了分子间和分子内氢键形成的两种类型的结构几何形状。
