Synthesis and photolysis of a series of substituted aroyl nitrogen ylides: development of photo-crosslinking and photolabeling reagents
摘要:
A series of substituted nitrogen ylides was prepared to study their suitability as photolabeling agents or as photo-cross-linking agents for biological systems. Two objectives were set in the design of these reagents: first, that they have a strong absorption beyond 320 nm, and second, that they be bifunctional so that they might be linked to the biological target before activation with light. Several systems were explored by analysis of their photochemical and photophysical properties. It was discovered that a biphenyl group-containing triazolium ylide satisfies these requirements.
