From Heteroaromatic Acids and Imines to Azaspirocycles: Stereoselective Synthesis and 3D Shape Analysis
Heteroaromatic carboxylic acids have been directly coupled with imines using propylphosphonic anhydride (T3P) and NEt(iPr)(2) to form azaspirocycles via intermediate N‐acyliminium ions. Spirocyclic indolenines (3H‐indoles), azaindolenines, 2H‐pyrroles and 3H‐pyrroles were all accessed using this met...
