A number of actinocin amides containing residues of aza-15-crown-5 and aza-18-crown-6 where crown fragments were separated
from the heterocyclic chromophore by the residues of ω-amino acids were obtained as actinomycin D models. 相似文献

A new approach for the synthesis of functionalized racemic 3,4-dihydroferroceno[c]pyridines via the Ritter reaction of 2-methyl-1-ferrocenylpropan-1-ol with nitriles in the presence of methansulfonic acid was developed. The scope and limitations of the reaction were evaluated. Selected racemic 3,4-dihydroferroceno[c]pyridines were successfully separated by preparative HPLC on a Chiralcel OD-H column. The absolute configuration of the enantiomers was determined by X-ray crystal structure analysis. 相似文献

Two types of chelating sorbents with different types of addition of iminodipropionate groups to a polymeric matrix were synthesized:
carboxyethylated aminopolystyrene (sorbent 1) based on linear polystyrene and carboxyethylaminomethylpolystyrene (sorbent 2) based on the copolymer of styrene and divinylbenzene. The ionization constants and concentrations of functional groups of
the sorbents (exchange capacity for hydrogen ions) were determined. The sorbents exhibit high selectivity for copper(II) ions
with the maximum of sorption from ammonia—acetate buffer solutions lying in a range of pH 5.0–7.5. The time needed for a solution
of copper(II)—sorbent system with continuous stirring to reach exchange equilibrium is 3.5 and 2 h for sorbents 1 and 2, respectively. The exchange capacity for copper(II) ions is 2.54 and 0.10 mmol g−1, respectively.
