Synthetic methods and compounds involving amino amides, peptides and peptidomimetics. Amino amide derivatives are prepared via the one-step three-component reaction of a glyoxamide, an amine, and an organoboron derivative. Conversion of the product to another glyoxamide intermediate allows the iterative use of this chemistry for the synthesis of peptides and peptidomimetics.

A technically simple approach for rapid, high-yielding and site-selective bioconjugation has been developed for both in vitro and cellular applications. This method involves the generation of maleimido-phosphonium ylides via 4-nitrophenol catalysis under physiological conditions followed by their Wittigreactions with aldehyde-appended biomolecules.
