Application

2-Methylbutyraldehyde can be used as a reactant to synthesize:
  • 2-amino-3-cyanopyridine derivatives via multicomponent condensation with various acetophenones and malononitrile in the presence of ammonium acetate.[1]
  • N,N-Diethyl-2-methyl-1-butanamine by reacting with diethylamine via Rh-catalyzed reductive amination reaction in the presence of molecular hydrogen.[2]
  • α-(2-Methylbutylidene)benzeneacetonitrile by condensation reaction with benzyl cyanide using tricyclic strong nonionic Lewis bases.[3]
