Title:
β−置換プロピオン酸アミド及びＮ−置換（メタ）アクリルアミドの製造方法
Document Type and Number:
Japanese Patent JP6869529
Kind Code:
B2
Abstract:
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-CH-C(R)H-C(=O)-OR(1), A-CH-C(R)H-C(=O)-N(R)R(3), CH=C(R)-C(=O)-N(R)R(7)SELECTED DRAWING: None
