Paragraph 0051; 0053; 0054, (2018/07/03)
PROBLEM TO BE SOLVED: To provide a method for industrially manufacturing β-alkoxy propionic acid amide, β-amino propionic acid amide and N-substituted (meth)acryl amide using (meth)acrylic acid ester as starting material at high yield and high purity. SOLUTION: There is provided a method for obtaining N-substituted (meth)acryl amide represented by target compound formula (7) by conducting an amidation reaction with amine using β-substituted propionic acid ester represented by the formula (1) of a product of a Michael addition reaction of (meth)acrylic acid ester and alcohol or amine in presence of a metal complex as a catalyst to obtain β-substituted propionic acid amide represented by the formula (3) and conducting a thermal decomposition reaction of β-substituted propionic acid amide in presence of the metal complex as the catalyst to eliminate alcohol or amine. A-CH2-C(R1)H-C(=O)-OR2 (1), A-CH2-C(R1)H-C(=O)-N(R3)R4 (3), CH2=C(R1)-C(=O)-N(R3)R4 (7) SELECTED DRAWING: None COPYRIGHT: (C)2018,JPOandINPIT

The novel efficient procedure has been developed for the conjugate addition of amines to electron deficient alkenes. The results showed that the catalyst was very efficient for the reactions with the excellent yields in several minutes. Operational simplicity, without need of any solvent, low cost of the catalyst used, high yields, reusability, excellent chemoselectivity, applicability to large-scale reactions are the key features of this methodology.
