Unexpected formation of 4,4,6-trimethyl-2-oxo-1-phenyl-1,2,3,4-tetrahydropyridine-3-carbonitrile via Tandem Knoevenagel condensation-Michael addition-intramolecular cyclization
摘要:
Knoevenagel condensation (Cope version) of acetone with cyanoacetanilide resulted in the formation of 4,4,6-trimethyl-2-oxo-1-phenyl-1,2,3,4-tetrahydropyridine-3-carbonitrile whose structure was determined by X-ray analysis.
