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)
