Glycerol was used as a reaction medium as well as promoter for aza-Michael addition of aromatic amines to electronic deficient α,β-unsaturated ketones. Various aromatic amines can react smoothly with chalcone, 2-cyclohexen-1-one, 2-cyclopenten-1-one, and ethyl vinyl ketone to achieve good to excellent yields in the absence of any catalyst.
甘油被用作反应介质,同时也是芳香胺与缺电子的α,β-不饱和酮的aza-Michael加成反应的
促进剂。多种芳香胺能够顺利地与
查尔酮、
2-环己烯-1-酮、2-
环戊烯-1-酮和乙基
乙烯酮反应,在无需任何催化剂的情况下实现优良至极佳的产率。
