  Copper-Mediated Transformation of Organosilanes to Nitriles with DMF and Ammonium Iodide

  摘要：

  Cyanation of aryl-, diaryldimethyl-, and styrylsilanes was developed for the first time under copper-mediated oxidative conditions using ammonium iodide and DMF as the combined source of nitrogen and carbon atom of the introduced cyano unit, respectively. The reaction was observed to proceed in a two-step process: initial conversion of organosilanes to their iodo intermediates and then cyanation. This method has a broad substrate scope with high functional group tolerance.

• Rhodium-catalysed addition of organotrialkoxysilanes to α-substituted acrylic esters

  日期：——

  The cationic rhodium complex [Rh(cod)2][BF4] effectively catalyses the 1,4-addition of organotrialkoxysilanes to alpha-substituted acrylic esters. The reactions are promoted by heating in an oil-bath or more conveniently in a microwave reactor allowing rapid access to a useful range of functionalised products including 2-alkyl succinates and alpha-amino acid derivatives.

• Peptide modification through site-selective residue interconversion: application of the rhodium-catalysed 1,4-addition of aryl siloxanes and boronates

  The site-selective interconversion of serine and cysteine residues of di- and tripeptides into phenylalanine derivatives, bearing a range of functionalities, has been achieved in high yield and selectivity through the common dehydroalanine intermediate. Through the application and development of the rhodium-catalysed 1,4-addition to alpha,beta-dehydroamino acid moieties with organometallic nucleophiles, a variety of peptides have been successfully modified to contain unnatural amino acid residues in predesignated residue positions.
