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... |

Arylation of diazoesters by a transient N-H insertion organocascade.
Angew. Chem. Int. Ed. Engl. 52(43) , 11317-20, (2013) It takes two: A unique organocatalyzed cascade for the unsymmetric double arylation of α-nitrodiazoesters is described. This organocascade features the strategic use of carbene-activating anilines in conjunction with a urea catalyst, thus allowing for the syn... |

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 ... |

Internal Lewis acid assisted ureas: tunable hydrogen bond donor catalysts.
Chem. Commun. (Camb.) 49 , 4289-4291, (2013) The strategic incorporation of internal Lewis acids onto urea scaffolds gives rise to a family of tunable hydrogen bond donor catalysts. The nature of the Lewis acid and associated ligands affects the urea polarization, acidity, and activity in reactions of n... |
