Abstract
A condensation reaction of 4-cyanobenzaldehyde (1) with methyl azidoacetate (2) in the presence of sodium methoxide produces a mixture of geometrical isomers of azidocinnamates 3 which undergoes thermolysis to give an indole 4. By contrast, the treatment of 2-cyanobenzaldehyde (5) with 2 in the presence of sodium methoxide and followed by the usual workup furnishes an azepine derivative 6.
