A Mild Ni/Cu-Catalyzed Silylation via C–O Cleavage
摘要:
A Ni/Cu-catalyzed silylation of unactivated C-O electrophiles derived from phenols or benzyl alcohols is described. This transformation is characterized by its wide scope and mild conditions, providing a direct access to synthetically versatile silylated compounds. The protocol allows for the coupling of C(sp(2))-O and even C(sp(3))-O bonds with similar efficiency.
Compositions such as pharmaceutical compositions and uses for peptide-drug conjugates are disclosed. Such compositions can deliver a drug, a peptide, or a conjugate thereof to a target region, tissue, structure or cell in cartilage.
