Abstract
Site-specific modification of peptides and proteins has wide applications in probing and perturbing biological systems. Herein we report that 1,2-aminothiol can react rapidly, specifically and efficiently with 2-((alkylthio)(aryl)methylene)malononitrile (TAMM) under biocompatible conditions. This reaction undergoes a unique mechanism involving thiol-vinyl sulfide exchange, cyclization, and elimination of dicyanomethanide to form...
