A highly selective method for the synthesis of asymmetrically substituted carbocycles and heterocycles from unactivated aldehyde-olefin precursors has been achieved via enantioselective SOMO-catalysis. Addition of a catalytically generated enamine radical cation across a pendent olefin serves to establish a general asymmetric strategy toward the production of a wide range of formyl-substituted ...

A Zn(II) macrocyclic complex with appended quinoline is a bifunctional recognition agent that uses both the Zn(II) center and the pendent aromatic group to bind to thymine in bulges with good selectivity over DNA containing G, C or A bulges. Spectroscopic studies show that the stem containing the bulge stays largely intact in a DNA hairpin with the Zn(II) complex bound to the thymine bulge.

kaposiform hemangioendothelioma is an aggressive endothelial-derived spindle cell neoplasm that occurs nearly exclusively during childhood and teenage years. the lesion grows rapidly and is often associated with kasabach-merritt syndrome. in this study a 24 days old male neonate who presented with an ill-defined deeply situated violaceous mass on his left arm is described. he had also anemia an...

Three linear polyesters with pendant ketoprofen were synthesized by copolymerization of polyethylene glycol (PEG) with malic acid (thiomalic acid or aspartic acid) using lipase B acrylic resin from Candida antarctica (CAL-B) at 90 °C respectively. These thermosensitive polyesters exhibit a lower critical solution temperature (LCST) at 10–12 °C. The in vitro study demonstrated that these polyest...

Let [Formula: see text] be a simple graph with vertices, edges having Laplacian eigenvalues text]. The energy LE[Formula: is defined as text], where the average degree of Radenković and Gutman conjectured that among all trees order path has smallest energy. family diameter In this paper, we show any tree greater than thereby proving conjecture for We also truth number non-pendent vertices at mo...

Platinum(II) complexes bearing various alkyne-pyrene, alkyne-4'-terpyridine and alkyne-dibutoxyphenylacetylide-terpyridine units were constructed in a step-by-step procedure based on copper-promoted cross-coupling reactions with preconstructed modules; formation of bis(ligand) complexes of Fe(II) and Zn(II) by binding of the pendent terpyridine units provided heterotrinuclear derivatives, all o...

The Wiener index of a graph G is defined as W (G) = ∑ u,v dG(u, v), where dG(u, v) is the distance between u and v in G, and the sum goes over all pairs of vertices. In this paper, we characterize the connected unicyclic graph with minimum Wiener indices among all connected unicyclic graphs of order n and girth g with k pendent vertices.

The asymmetric unit of the title compound, C(26)H(28)BrN, contains two independent mol-ecules in which the carbazole rings are almost planar, with r.m.s. deviations of 0.0212 (1) and 0.0229 (1) Å. The dihedral angles between the carbazole ring system and the pendent benzene ring are 60.5 (1) and 56.3 (1)° in the two mol-ecules. In the crystal, mol-ecules are linked into chains along the b axis ...
