Photoaffinity tags can be incorporated easily into peptoids and
congeners by the Ugi and Passerini multicomponent reactions. Products
related to photo-methionine and photo-leucine can be accomplished
by diazirine-containing building blocks. The same protocols can
be used to synthesize derivatives with benzophenone photo cross-linkers.
