Isoquinoline 2-oxide (1) reacts with cyanoacetic acid in the presence of Ac2O to afford various types of 1-substituted isoquinolines (2, 4, 6, and 7) and N-ylides (3 and 5a) depending upon the reaction conditions and processing procedures (Table I).The reaction in Ac2O gives initially alpha-acetoxycarbonyl-1-isoquinolineacetonitrile (2) and 2-isoquinolinio-acetoxycarbonylcyanomethylide (3), and that in Ac2O-dimethylformamide yields only 3.Products 2 and 3 are readily convertible into alpha-acetyl-1-isoquinolineacetonitrile (4) and 2-isoquinolinio-acetylcyanomethylide (5a), respectively, by processing involving heating.The reaction in ethanol gives ethyl alpha-cyano-1-isoquinolineacetate (6) and di(1-isoquinolyl)acetonitrile (7).The reaction of 1 with benzoylacetonitrile affords both the corresponding 1-substituted isoquinoline (10) and N-ylide (11).Reactions with ethyl benzoylacetate and, methyl and ethyl acetoacetates produce 1-substituted isoquinolines (12 and 14a, b) and 4-acetoxyisoquinoline (13), no ylide being formed.Keywords – isoquinoline 2-oxide; nucleophilic reaction; decarboxylative acyl migration; alpha-acetoxycarbonyl-1-isoquinolineacetonitrile; alpha-acetyl-1-isoquinolineacetonitrile; ethyl alpha-cyano-1-isoquinolineacetate; alpha-benzoyl-1-isoquinolineacetonitrile; 2-isoquinolinio-acetoxycarbonylcyanomethylide; 2-isoquinolinio-acetylcyanomethylide; 2-isoquinolinio-benzoylcyanomethylide.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 1532-72-5, you can also check out more blogs about1532-72-5
