dc.description.abstract | The asymmetric 1,2-addition of formyl anion equivalents to carbonyl compounds is a powerful synthetic
tool that ideally provide access to highly functionalizable a-hydroxy aldehydes in an enantioselective fashion.
In this context, the nucleophilic character of formaldehyde hydrazones, together with their remarkable
stability as monomeric species, has been exploited for the functionalization of diverse carbonyl compounds,
using initially auxiliary-based methodologies and, more recently, catalytic enantioselective versions. This
feature article highlights our research progress employing formaldehyde tert-butyl hydrazone as a versatile
formyl anion equivalent, in combination with bifunctional H-bonding organocatalysis. The design and
optimization of different catalytic systems, focusing on a dual activation of both reagents, is reviewed, as
well as the racemization free unmasking of the formyl group and representative product transformations for
the construction of valuable, densely functionalyzed chiral building blocks. | es |
