Abstract (AI)
Abstract Cyanoacetamide undergoes a Knoevenagel condensation reaction with β‐ketoanilides 2a – c to give the acyclic products 3a – c . The reactivity of 3a towards the active methylene reagents, aldehydes, aryldiazonium salts and cinnamonitrile derivatives were studied.
Key Findings
1
Cyanoacetamide undergoes Knoevenagel condensation with β-ketoanilides 2a–c to produce acyclic products 3a–c.
2
The reactivity of product 3a was investigated with active methylene reagents, aldehydes, aryldiazonium salts, and cinnamonitrile derivatives.
3
These reactions provide synthetic routes toward polyfunctionally substituted pyridine and coumarin derivatives.
