General description

Isobutyraldehyde is an α,α-disubstituted aldehyde. It is an important raw material for the manufacture of various industrially important chemicals. It may be produced from CO2 and overexpression of ribulose 1,5-bisphosphate carboxylase/oxygenase employing genetically engineered strain of Synechococcus elongatus PCC7942. Enantioenriched γ-nitroaldehydes are obtained from the conjugate addition reaction between isobutyraldehyde with nitroalkenes in the presence of chiral organocatalysts.

Application

Isobutyraldehyde may be used in the synthesis of the following compounds:
  • N-cyclohrxyl-α-dimethylaminoisovalerarnide
  • N′-cyclohexyl-N,N-dimethyl-α-dimethylaminoisovaleramidine
  • α-acetoxy-N-cyclohexylisovaleramide
  • acetic anhydride
  • N-cyclohexyl-a-formyloxyisovaleramide
  • cyclic carbonates
  • hydroxypivaldehyde, which is useful for the preparation of neopentyl glycol (NPG)
It may also be employed for the microbial synthesis of isobutanol.

Electronically excited triplet carbonyls are formed during the oxidative degradation of polyunsaturated fatty acids, amino acids, and beta-dicarbonyl metabolites. Due to their long lifetime and high alkoxyl radical-like reactivity, triplet carbonyls may initiate deleterious reactions in biological systems. Here we
