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.

Org. Lett. 12(23) , 5442-5, (2010)

On lithiation with lithium amides, N-allyl-N'-aryl ureas undergo rearrangement with transfer of the aryl ring from N to the allylic α carbon. From the α-arylated products, a further aryl transfer unde...

A new synthesis of imidazolidin-2-ones via Pd-catalyzed carboamination of N-allylureas.

Org. Lett. 8(12) , 2531-4, (2006)

A new strategy for the preparation of substituted imidazolidin-2-ones in two steps from readily available N-allylamines is described. Addition of the amine starting materials to isocyanates affords N-...
