Base Formation

The biosynthesis of the newly isolated polyamine, sym-homospermidine (NH2–[CH2]4–NH–[CH2]4 –NH2), was studied by using radioactive amino acids. Arginine was the most effective precursor, being about 10 times as active as ornithine. Unlabelled agmatine and putrescine markedly inhibited the incorporation of [14C]arginine into homospermidine. Similarly the incorporation of ornithine was inhibited by unlabelled arginine and putrescine. γ-Aminobutyraldehyde, the oxidation product of putrescine, was considered to be one of the intermediates in the biosynthesis of homospermidine. The biosynthesis may involve a Schiff-base formation of putrescine with γ-aminobutyraldehyde and subsequent reduction. A limited synthesis of spermidine also takes place under these conditions.

Abstract β-Phenylalanine forms with chloro bridged complexes the chiral N, O-chelates Cp*Ir(Cl)(NH2CH(Ph)CH2CO2) and (p-cymene)Ru(Cl)(NH2CHPhCH2CO2) as mixture of two diastereoisomers. Similarly the palladium(III) and platinum(II) complexes (Et3P)(Cl)M(NH2CH(Ph)CH2CO2) (M = Pd, Pt) were obtained. Schiff base complexes (arene)(Cl)M(O2CC(R)=N-CH(R)CH(R)CH2CO2CH3) (arene = Cp*, p-cymene; M = Ir, Ru) were synthesized from the chloro-bridged compounds, 2-oxocarboxylates and β-alanine or β-phenylalanine methylester. The Cp*Ir complex with a tridendate dianionic Schiff base generated from pyruvate and β-phenylalaninate is obtained as a single isomer. Cp*Ir(Cl) forms a complex with an N, O-bidentate Schiff base ligand from glycinate and acetylacetic ethyl ester.
