The scope and limitations of the isonitrile‐based NHC template synthesis were investigated with a series of precursors containing a nucleophilic amine in combination with tethered electrophiles. In the case of alkynes and phosphonic esters as electrophiles no ring closure was observed and new functionalized NAC gold complexes were obtained. By the use of unsaturated esters and phosphonic esters as

The present invention relates to the field of total chemical synthesis of ubiquitin and related peptides. More in particular, a method is provided of solid phase synthesis of ubiquitin, ubiquitin mutants and derivatives thereof. It was the object of the present invention to provide an approach for the total chemical synthesis of ubuiqitin, which allows for the chemical synthesis of virtually any Ub mutant and giving high overall efficiency and purity. The present inventors have surprisingly found that this object can be realized with a method relying on incorporation of special amino acid building blocks. This approach was found to allow for exceptionally high yields of up to 14% and to provide an synthetic entry into virtually any ubiquitin derivative.

Visible Light‐Mediated Synthesis of Enantiopure γ‐Cyclobutane Amino and 3‐(Aminomethyl)‐5‐phenylpentanoic Acids
Density functional theory calculations shed light on the conformational prerequisites for the [2+2] photocycloaddition. The bicyclic key structures could be readily transformed into γ‐cyclobutane amino acids.
