Descrição

Descrição geral

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.

Aplicação

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.
