Abstract

In recent years, bifunctional catalysis has proven to be a successful concept in asymmetric organocatalysis.[1] In particular, various highly efficient asymmetric catalytic protocols have been designed and implemented based on this concept by using (thio) urea-type bifunctional catalysts.[2, 3] The combination of the double hydrogen-donating (thio) urea group with a Brønsted or Lewis basic group in these catalysts is the key for dual chemical ...
