Imino Compound Preparation TRIZ Cases
- DON Prodrug Synthesis via Late-Stage Diazotization
Introducing the diazo group late in the pathway prevents intermediate cyclization, ensuring high chemical purity and enantiomeric excess.
- 3-Fluoroalkyl-5-Pyrazolecarboxylate Synthesis via Ketimine Cyclization
Ketamine intermediates react with oxalic acid derivatives to form pyrazole rings, resolving low yield issues in traditional acrylic routes.
- Aldehyde Mixture Blocking Agents for Polyurethane Latent Hardeners
Volatile aldehyde mixtures block amines to eliminate plasticizer migration and bubble formation in single-component polyurethane systems.
