In a novel organocatalytic formal [3 + 2] cycloaddition to afford chiral 2-oxazolidinones, an enantioselectivity switch could be induced by changing the manner of addition of the reactants, even when the reaction components (cinchona-alkaloid-derived aminothiourea catalyst, substrates, and solvent) were the same.

New mixed alkyl benzyl imidodicarbonates were prepared by reaction of benzyloxycarbonyl isocyanate with appropriate alcohols.This simple procedure also furnished alternative, more convenient routes to dibenzyl and benzyl 9-fluorenylmethyl imidodicarbonates.The substances are of interest as potential Gabriel reagents.Completely selective removal of one of the alkoxycarbonyl groups from the N-atom of the imidodicarbonates was demonstrated in several instances, giving benzyl carbamate or the alternative carbamate.
