应用
1-(3,5-bis(trifluoromethyl)phenyl)-3-(2-(difluoroboryl)phenyl)urea is a robust and user-friendly white solid capable of being stored on the benchtop indefinitely. The strategic incoporation of the difluoroboryl substituent renders this the most acidic urea catalyst reported to date (pKa(DMSO) = 7.5). This difluorboronate urea benefits from enhanced reaction rates and yields when compared to traditional urea catalysts. It also enables reactions that are inaccessible with conventional urea catalysis.

Highly functionalized oxazinanes are efficiently prepared through urea-catalyzed formal [3 + 3] cycloaddition reactions of nitrones and nitrocyclopropane carboxylates. The reaction system is general with respect to both the nitrocyclopropane carboxylates and nitrones enabling the preparation of a large family

The power of hydrogen-bond donor catalysis has been harnessed to elicit and control carbene-like reactivity from nitrodiazoesters. Specifically, select ureas have been identified as effective catalysts for N-H insertion and multicomponent coupling reactions of nitrodiazoesters, anilines, and aromatic nucleophiles, thereby

Boronate ureas benefit from internal Lewis acid coordination of the urea cabonyl oxygen and the strategically placed boron. As a result of this structural feature, boronate ureas can be rendered more acidic than conventional urea hydrogen bond donor catalysts.
