Synthetic and Mechanistic Aspects on the Wittig Reaction. A Yield Increasing Modification.

Enabling Wittig reaction on site-specific protein modification.

An efficient aqueous Wittig reaction was enabled on protein bioconjugation for the first time. By investigating the reaction on small molecules, peptides, and proteins, a site-specific reaction targeting "aldehyde tag" was presented. A variety of functional groups could be introduced into the protein of interest.

The Wittig Reaction

The Wittig Reaction

This so-called Wittig reaction has a number of advantages over other olefination methods; in particular, it occurs with total positional selectivity (that is, an alkene always directly replaces a carbonyl group). By comparison, a number of other carbonyl olefination reactions often occur with double-bond rearrangement. In addition, the factors that influence Eand Z-stereoselectivity are well un...
