  Staudinger-Phosphonite Reactions for the Chemoselective Transformation of Azido-Containing Peptides and Proteins

  摘要：

  Site-specific functionalization of proteins by bloorthogonal modification offers a convenient pathway to create, modify, and study biologically active biopolymers. In this paper the Staudinger reaction of aryl-phosphonites for the chemoselective functionalization of azido-peptides and proteins was probed. Different water-soluble phosphonites with ollgoethylene substituents were synthesized and reacted with unprotected azido-containing peptides in aqueous systems at room temperature in high conversions. Finally, the Staudinger-phosphonite reaction was successfully applied to the site-specific modification of the protein calmodulin.
