Повний текст джерелаThis thesis describes the use of copper and palladium to mediate transformations of carboranes, especially p-carborane.
1-(1-p-carboranyl)-N-methyl-N-(2-butyl)-3-isoquinolinecarboxamide, a carborane containing analogue of the peripheral benzodiazepine receptor (PBR) ligand PK11195, has been synthesised. A key step in the reaction is the copper (I) mediated coupling of p-carborane with ethyl 1-bromo-isoquinoline-3-carboxylate.
p-Carborane has been arylated on the 2-B-atom in high yields, using the Suzuki–Miyaura reaction. Thus the reaction between 2-I-p-carborane and various arylboronic acids [1-naphthyl-, phenyl-, 4-MeO-C6H4-, 3-CH3CONH-C6H4-, 4-NC-C6H4-, 3-NO2-C6H4-], gave the corresponding 2-aryl-p-carboranes in DME solution when reacted in the presence of cesium fluoride and the catalytic Pd2(dba)3–dppb system. Under the same conditions, the boron-boron bond forming reaction of two p-carboranylboronic esters (2-[(pinacolato)boron]-p-carborane and 2-[(neopentyl glycolato)boron]-p-carborane) was also shown feasible.
p-Carborane has been vinylated on the 2-B-atom in high yields by use of the Heck reaction. The coupling between 2-I-p-carborane and various styrenes [4-H-, 4-C6H4-, 4-Cl , 4-Br-, 4-NO2-, 4-CH3O- and 4 CH3 ] resulted in the formation of the correspondingtrans-β-(2-B-p-carboranyl) styrene in DMF solution when reacted in the presence of silver phosphate and the palladacycle Herrmann´s catalyst. The reaction was shown to proceed at higher rate with electron rich than with electron deficient olefins.
The feasibility of palladium-catalysed isotopic exchange of an iodinated closo-carborane with a radioisotope of iodine has been studied. 2-I-p-carborane was selected as a model compound. It was shown, that such isotopic exchange is possible and provides a high yield (83 ± 4.2 %) during 40 min long reaction. The reaction conditions were optimised, and it was demonstrated that presence of the tetra n-butylammonium hydrogensulphate is important in order to stabilise catalyst and provide reproducibility of labelling. In this work we have modified the methodology and extended the application to a wider range of iodinated carboranes. By the use of Herrmann’s catalyst in toluene at 100 °C this [125I]-iodide labelling could be improved and extended. 2-I-p- 9-I-m-, 9-I-o-, 3-I-o-carborane, 1-phenyl-3-I-o-carborane and 1,2-diphenyl-3-I-o-carborane could be [125I]-iodide labelled in high to excellent yields within 5 minutes.This reported palladium catalyzed radio-iodination of the uncharged closo-carboranes might find use in pharmacokinetic studies of carborane derivatives.

Повний текст джерелаCopper(II) complexes of bis(2-pyridylmethyl)amine (Cu(II)bpa), N-(2-hydroxyethyl)bis(2-pyridylmethyl)amine (Cu(II)hebpa) and N-(3-hydroxypropyl)bis(2-pyridylmethyl)amine (Cu(II)hpbpa) have been synthesized and their reactivities and mechanisms for cleaving bis(2,4-dinitrophenyl) phosphate (BDNPP) have been investigated. Cu(II)hpbpa is observed to be the most reactive (k = 7.2 $ times$ 10$ sp{-1}$ M$ sp{-1}$ s$ sp{-1}$ at 25$ sp circ$C, pH 8.8) for cleaving BDNPP followed by Cu(II)bpa (k = 2.0 $ times$ 10$ sp{-2}$ M$ sp{-1}$ s$ sp{-1}$) and Cu(II)hebpa (k = 2.0 $ times$ 10$ sp{-2}$ s$ sp{-1}$). HPLC product analyses indicated that Cu(II)hpbpa cleaves BDNPP mostly through transesterification while the complexes Cu(II)bpa and Cu(II)hebpa cleave BDNPP predominantly by hydrolysis. The differences in the mechanisms and the reactivities are explained in terms of the differences in the structures of the three copper(II) complexes.
Copper(II) complexes of 1,8-bis(1,4,7-triazacyclononyl-N-methyl)naphthalene (tntn), 1,4,7-triazacyclononane (tacn), and N-benzyl-1,4,7-triazacyclononane (btacn) have been prepared and their reactivities compared for cleaving RNA. The novel dinuclear copper(II) complex, Cu(II)$ sb2$tntn, is observed to be 200-500 fold faster per metal center than the mononuclear copper(II)complexes, Cu(II)tacn and Cu(II)btacn, for cleaving a diribonucleotide, ApA, and its cyclic phosphate intermediate, $2 sp prime3 sp prime$-cAMP. Cu(II)$ sb2$tntn (2.0 mM) reduces the half life of ApA (0.05 mM) to 50 minutes (pH 6, 50$ sp circ$C); this represents a rate acceleration of approximately 10$ sp5$ fold over the background hydroxide rate. The half life of $2 sp prime3 sp prime$-cAMP (0.05 mM) is decreased to 4 minutes in the presence of Cu(II)$ sb2$tntn (2.0 mM, pH 6, 25$ sp circ$C); this represents a rate acceleration of about 10$ sp8$ fold over the background hydroxide rate.
