General description

Aldol addition of enolizable 1,3-dicarbonyl compounds to 2-cyanobenzaldehyde in the presence of a tertiary amine has been reported. Biotransformation of 2-cyanobenzaldehyde by Euglena gracilis Z cultured photohetero-trophically has been reported.

Application

2-Cyanobenzaldehyde may be used:
  • in the base-catalyzed one-pot synthesis of 3-substituted isoindolinones
  • in the synthesis of 3-oxo-2,3-dihydro-1H-isoindoles, via Baylis-Hillman reaction
  • in the synthesis of 3-(N-substituted amino)-1-isoindolenones

The mechanism of a base-catalyzed one-pot reaction of 2-cyanobenzaldehyde and primary nitroalkanes, to produce 3-substituted isoindolinones, has been investigated. A route starting with a nitroaldol (Henry) reaction, followed by a subsequent cyclization and rearrangement, was supported by intermediate analogue synthesis
