Cationic dirhodium carboxylate-catalyzed synthesis of dihydropyrimidones from propargyl ureas.

Author information

Department of Chemistry, University of Utah, Salt Lake City, UT 84112, United States.


Cationic Rh(II) complexes are able to catalyze the regioselective hydroamination of propargyl ureas in a 6-endo fashion. This transformation permits access to interesting substitution patterns of dihydropyrimidines which have found use as nucleotide exchange factor inhibitors.
