| titleOfInvention | Preparation method of beta-amino acrylonitrile compound |
| abstract | The invention discloses a preparation method of beta-amino acrylonitrile compounds. It comprises the following steps: in a solvent, reacting beta-amino cyanoacrylate shown as a formula I under the action of a catalyst to obtain a beta-amino acrylonitrile compound shown as a formula II; wherein R is 1 Is C1-C12 alkyl, halogenated C1-C12 alkyl, C3-C12 cycloalkyl, C2-C12 alkenyl, C2-C12 alkynyl, aryl, substituted aryl, benzyl or substituted benzyl; r 2 Is hydrogen, halogen, hydroxyl, amino, cyano, nitro, C1-C12 alkyl or halogenated C1-C12 alkyl. The method has the characteristics of good stereoselectivity, high yield, simple preparation of the raw material beta-amino cyanoacrylate and the like, and has great practical value. |
