Cross-Coupling of Secondary Amides with Tertiary Amides: The Use of Tertiary Amides as Surrogates of Alkyl Carbanions for Ketone Synthesis

In recent years, exciting progress has been made in the field of direct transformation of amides, nevertheless, the condensation between two amides remains rare and restricted to homo-coupling reactions. Herein, we report the cross-coupling of secondary amides with tertiary amides, which provides a synthesis of ketones under mild conditions, and features the use of tertiary amides as surrogates of alkyl carbanions. The method relies on the coupling of enamines, generated from tertiary amides by catalytic partial reduction of tertiary amides with Vaska's catalyst, with nitrilium ions, formed in situ from secondary amides via activation with trifluoromethanesulfonic anhydride, and on the subsequent deformylation.

Scope and Pathway of Catalytic Aminomethylation of Olefins
Jachimowicz, Felek,Raksis, Joseph W.
, p. 445 - 447 (2007/10/02)
We describe a general and high-yield one-step process for synthesis of tertiary and secondary amines from olefins, carbon monoxide, water, and a nitrogen source in the presence of transition-metal compounds as catalysts.We find this chemistry, initially d
