Boronate ureas operate as catalysts for the activation of nitrocyclopropane carboxylates in nucleophilic ring-opening reactions. A variety of amines were found to open the urea-activated nitrocyclopropane carboxylates, generating highly useful nitro ester
Internal lewis acid assisted hydrogen bond donor catalysis
So, Sonia S.,Burkett, Julie A.,Mattson, Anita E.
supporting information; experimental part, p. 716 - 719 (2011/04/24)
Boronate ureas are introduced as a new class of noncovalent catalysts for conjugate addition reactions with enhanced activity. Through intramolecular coordination of the urea functionality to a strategically placed Lewis acid, rate enhancements up to 10 t
