Synthesis of structural variants of Staphylococcus aureus lipoteichoic acid (LTA)

Based on 1,2-O-isopropylidene-sn-glycerol, which is readily available from d-mannitol, five chiral building blocks for the construction of structural variants of Staphylococcus aureus LTA designed and synthesized. Ligation of these building blocks led readily to the target molecules 1 and 2. They demonstrated that the d-alanine residues at the glycerophosphate backbone are decisive for the activation of the immune system.

Unprotected Amino Acids as Stable Radical Precursors for Heterocycle C-H Functionalization

An efficient and general method for the C-H alkylation of heteroarenes using unprotected amino acids as stable alkyl radical precursors is reported. This one-pot procedure is performed open to air under aqueous conditions and is effective for several natural and unnatural amino acids. Heterocycles of varying structure are suitably functionalized, and reactivity trends reflect the nucleophilic character of the radical species generated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1121-79-5 is helpful to your research. Reference of 1121-79-5

Crystal structure of catena-poly[[[(2-ethoxypyrazine-kappaN)copper(I)]-di-mu2-cyanido] [copper(I)-mu2-cyanido]]

In the asymmetric unit of the title coordination compound, {[Cu(CN)(C4H3OC2H5N2)][Cu(CN)]} n, there are two Cu atoms with different coordination environments. One CuI ion is coordinated in a triangular coordination geometry by the N atom of the 2-ethoxypyrazine molecule and by two bridging cyanide ligands, equally disordered over two sites exchanging C and N atoms, thus forming polymeric chains parallel to the c axis. The other Cu atom is connected to two bridging cyanide groups disordered over two sites with an occupancy of 0.5 for each C and N atom, and forming an almost linear polymeric chain parallel to the b axis. In the crystal, the two types of chain, which are orthogonal to each other, are connected by cuprophilic Cu..Cu interactions [2.7958 (13) A], forming two-dimensional metal-organic coordination layers parallel to the bc plane. The coordination framework is further stabilized by weak long-range (electrostatic type) C-H..pi interactions between cyano groups and 2-ethoxypyrazine rings.
