The invention discloses an acryloyl-N-isopropylglycinamide monomer and a preparation method thereof. Specifically, N-(tert-butoxycarbonyl) glycine methyl ester, isopropylamine and acryloyl chloride are used as raw materials and react under a certain condition to generate acryloyl-N-isopropylglycinamide. The acryloyl-N-isopropylglycinamide has double bonds and can be subjected to free radical polymerization. Meanwhile, acryloyl-N-isopropylglycinamide has hydrophobic isopropyl and two hydrophilic amide groups, and the hydrophilic amide groups can provide a double hydrogen bond structure. Isopropyl can endow polymer molecules with temperature characteristic similar to that of poly (N-isopropylacrylamide), and the double hydrogen bond structure enables multiple hydrogen bond effects to be achieved between polymer molecules and in molecules. Therefore, the monomer can be polymerized to form a polymer, so that a polymer material with special temperature sensitivity is obtained, and the polymer material has potential application value in the field of bioengineering.

This paper describes a new amino-amide-based transient directing group (TDG). The TDG can exhibit better performance in the Pd-catalyzed arylation of aliphatic aldehydes and ketones. This reaction showed good substrate compatibility and regioselectivity. The results indicated that 3-amino-N-isopropylpropionamide was more beneficial to the β-arylation of aliphatic aldehydes than other TDGs under relatively mild conditions.
Oligomeric epoxide-amine adducts based on 2-amino-N-isopropylacetamide and a-amino-ε-caprolactam: Solubility in presence of cyclodextrin and curing properties

2-Amino-N-isopropylacetamide and α-amino-ε-caprolactam were reacted with glycerol diglycidyl ether to give novel oligomeric thermoresponsive epoxide-amine adducts. These oligomers exhibit a lower critical solution temperature (LCST) behavior in water. The solubility properties were influenced with randomly methylated β-cyclodextrin (RAMEB-CD) and the curing properties of the amine-epoxide mixtures were analyzed by oscillatory rheology and differential scanning calorimetry, whereby significant differences in setting time, viscosity, and stiffness were observed.
