Lewis base-catalyzed reaction of aziridinofullerene with ureas for the preparation of fulleroimidazolidinones

The Lewis base-catalyzed double nucleophilic substitution reaction of N-tosylaziridinofullerene with various ureas allows the easy preparation of fulleroimidazolidinones with a high tolerance for functional groups. Alkyl-substituted ureas show better reactivity than aryl-substituted ureas.

Lewis Acid Catalysed Preparation of some Carbamates and Sulphonylureas. Application to the Determination of Enantiomeric Purity of Chiral Alcohols

Lewis acids such as boron trifluoride-diethyl ether and aluminium chloride catalyze the reaction of alcohols and sulphonamides with isocyanates, affording carbamates and sulphonylureas, respectively, in acceptable yield.Applied to the formation of diastereoisomeric carbamates from chiral alcohols using Pirkle's reagents, , this technique provides a convenient method for determination of enantiomeric purity.
