Ligand-Controlled Regiodivergent Hydroformylation of Ynamides: A Stereospecific and Regioselective Access to 2- and 3‑Aminoacroleins
journal contribution
posted on 2019-10-18, 14:06 authored by Patrick Wagner, Morgan Donnard, Nicolas GirardThe rhodium-catalyzed
hydroformylation of ynamides is described
and gives selective access to 2- or 3-aminoacrolein derivatives. The
regioselectivity of this carbonylation can be completely controlled
at will thanks to the nature of the ligand used. This represents the
first example of regiodivergent alkyne hydroformylation. The influence
of the substituents on the different positions of the ynamide has
been investigated, and it appears that this reaction is tolerant to
a wide range of functional groups.
