—— | 5-hydroxy-4,5-dimethyl-2-oxo-1-(2-(phenyl)ethyl)-2,5-dihydro-1H-pyrrole-3-carbonitrile | 913819-76-8 | C15H16N2O2 | 256.304 |
N-Substituted cyanoacetamides 1 were condensed with 1,2-diketones 2 under base catalysis to form γ-hydroxy γ-lactams 3. Treatment of 3 with acids gave novel fungicidal γ-methylene γ-lactams 4. The exocyclic double bond of 4b reacted reversibly with 4-toluene sulfinate.
