The telomerization of α, β, γ, and ε-amino acids having various structures with butadiene under the influence of the three-component palladium catalyst Pd(acac)2-PPh3-AlEt3 was investigated in DMSO-toluene solution.The α and ε-aliphatic and also the α, β, and γ-aromatic amino acids react with butadiene, giving the products from octadienylation at the amino group exclusively.Under the conditions of telomerization aliphatic β-amino acids are cleaved with the formation of unsaturated tertiary amines. in the case of aliphatic γ-amino acids it is possible to obtain telomers alkylated at the carbonyl group.
