• Dual enzyme biocatalyst

  A range of enantiomerically pure chiral amines have been prepared by a collaboration of scientists in the UK and the US. Nicholas Turner and Matthew Truppo from the University of Manchester and a co-worker from Codexis Incorporated, California, have synthesised a range of enantiomerically pure (R)- more

• Alternative to high cost palladium catalysts?
  

  Scientists in the USA have developed a ligand-free copper catalysed procedure for carbon-nitrogen bond formation. Christian Wolf and Hanhui Xu from Georgetown University, Washington, in the US, show that carbon-nitrogen bond formation can be achieved in high yield by a copper catalysed coupling pro more

• Chitosan conjugates for DNA delivery

  Graft copolymers of chitosan and maltodextrin were synthesized by reductive amination of a low molecular weight chitosan. The degree of substitution is 70% or above, as quantified by nuclear magnetic resonance spectroscopy, at molar ratios of chitosan glucosamine units and maltodextrin of 1 [ ] : [ more

• Neoglycoproteins as Carbohydrate Antigens: Synthesis, Analysis and Polyclonal Antibody Response

  The analysis and polyclonal antibody response for newly synthesized maltose – BSA conjugate neoglycoproteins is described. In this first, proof of concept study a simple carbohydrate antigen, maltose, was linked to bovine serum albumin by reductive amination. An aglycone spacer was utilized to con more

• ChemInform Abstract: Iron(II) Bromide‐Catalyzed Intramolecular C—H Bond Amination [1,2]‐Shift Tandem Reactions of Aryl Azides.

  Abstract Iron(II) bromide promotes tandem C—H bond amination 1,2‐migration reactions of ortho‐substituted aryl azides to enable the formation of various 2,3‐disubstituted indoles. more
