Chiral isocyanoazides: Efficient bifunctional reagents for bioconjugation

Nenajdenko, Valentine G.,Gulevich, Anton V.,Sokolova, Nadezhda V.,Mironov, Andrey V.,Balenkova, Elizabeth S.

supporting information; experimental part, p. 1445 - 1449 (2010/05/18)

Chiral scaffolds combining isocyanide and azide groups can be effectively synthesized to permit the efficient construction of both amino (hydroxy) acids and triazole derivatives, which enables the preparation of hybrid peptide molecules by Ugi/ click or click/Ugi strategies.
