The first NMR structure of a Cu(I)-bound metallochaperone model with the conserved sequence MT/HCXXC revealed that at pH ∼3.0 and ∼6.8 Cu(I) binds through one Cys and the Met rather than the two Cys residues, differently than at pH ∼8.5. This suggests a possible role of Met in metal transport.
The application of a variety of iron complexes with chelating amine ligands as pre-catalysts in the representative cross-coupling of 4-tolylmagnesium bromide with cyclohexyl bromide was investigated. The results from this study indicate the performance of the pre-catalyst is inversely proportional to the strength of the chelate or macrocyclic effect of the amine ligand, as determined by the pro...
Soluble copper phthalocyanine (CuPc) and naphthalocyanine (CuNc) precursors which can be converted thermally and photochemically into insoluble CuPc and CuNc, respectively, have been synthesized by a one-step reaction using commercially available chemicals.
A reagent-controlled enantioselectivity switch was uncovered in the asymmetric α-fluorination of β-ketocarbonyls by a chiral primary amine catalyst. By a simple swap of fluorination reagents, both enantiomers of the quaternary fluorination adducts could be obtained with good yields and high enantioselectivity. Mechanistic studies disclosed dual H-bonding and electrostatic stereocontrolling mode...
In search of new erythromycin derivatives 3-O-[gamma-(4-oxo-2-aryl-thiazolidin-3-yl)butyryl]erythromycin A derivatives have been synthesized. The 3-hydroxy group was derivatised to a primary amine and subsequently the thiazolidinone nucleus was generated at the amino functionality through DCC mediated one-pot three-component reaction in good yields.
The title compound, C(18)H(14)N(4)O(2), was found as a by-product in the nitro-aldol reaction between 2-(nitro-meth-yl)pyridine and N-(pyridin-2-ylmethyl-idene)methane-amine. Its two stereogenic centers give rise to four stereoisomers of which only the anti isomers are found in this crystal structure.
In the title cationic Cp(*)Fe(II) complex, [Fe(C(10)H(15))(CH(3)CN)(C(14)H(16)NP)]PF(6)·C(4)H(8)O, the metal ion is coordinated by the η(5)-Cp* ring as well as the P and N atoms of the chelating 2-(diphenyl-phosphino)ethyl-amine ligand and an additional acetonitrile mol-ecule in a piano-chair conformation. The PF(6) (-) anion is disordered over two sets of sites with occupancies of 0.779 (7) an...
Annulated thiophene perylene bisimides and their triphenyl-amine based oligomers have been synthesized. One of the oligomers FPTTPA has been demonstrated to be an efficient electron donor in bulk heterojunction (BHJ) organic solar cells, giving a power conversion efficiency of 1.42%.
The structure of the title compound, C(6)H(5)I(2)N, shows a weak inter-molecular amine-amine N-H⋯N hydrogen-bonding inter-action, giving a helical chain which extends along the a axis. An intra-molecular N-H⋯I hydrogen bond is also observed.
The μ-amino-borane complexes [Rh2 (L(R) )2 (μ-H)(μ-H2 B=NHR')][BAr(F) 4 ] (L(R) =R2 P(CH2 )3 PR2 ; R=Ph, (i) Pr; R'=H, Me) form by addition of H3 B⋅NMeR'H2 to [Rh(L(R) )(η(6) -C6 H5 F)][BAr(F) 4 ]. DFT calculations demonstrate that the amino-borane interacts with the Rh centers through strong Rh-H and Rh-B interactions. Mechanistic investigations show that these dimers can form by a boronium-me...
