Chiral
bis(guanidino)iminophosphoranes were designed and
synthesized as chiral uncharged organosuperbase catalysts that
facilitate activation of less-acidic pro-nucleophiles. The newly developed
bis(guanidino)iminophosphoranes, which possess the highest basicity
among chiral organocatalysts reported to date, were proven to be a
superb class of chiral organosuperbases by reaction of azodicarboxylates
with 2-alkyltetralones and their analogues as the less acidic pro-nucleophiles.
