Reactivity of Heterocyclic Enaminones: Regioselective Synthesis of Some Pyridobenzodiazepines and Imidazopyridines
摘要:
Reactivity of enaminones derived from various diaminopyridines toward electrophilic carbons (imines, carbodiimides, isocyanates) is reported. The reactions leading to diazepinic or imidazolic ring systems are shown to be dependent of the electrophilic species as well as of the position of the nitrogen atom in the heterocyclic ring.
