Ureido-derivatized polymers based on both poly(allylurea) and poly(L-citrulline) exhibit UCST-type phase transition behavior under physiologically relevant conditions.

Biomacromolecules 12(10) , 3418-22, (2011)

There are few examples of polymers that exhibit upper critical solution temperature (UCST) behavior under physiological conditions of temperature, pH, and ionic strength. In this study, we demonstrate...

Sequential double α-arylation of N-allylureas by asymmetric deprotonation and N→C aryl migration.
