Urea-catalyzed N-H insertion-arylation reactions of nitrodiazoesters.

J. Org. Chem. 79(11) , 4832-42, (2014)

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 o...

Urea-catalyzed construction of oxazinanes.

Org. Biomol. Chem. 11(35) , 5793-7, (2013)

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 ...
