Highly chemoselective metal-free reduction of tertiary amides.
This communication describes the chemoselective metal-free reduction of tertiary amides to the corresponding amines. Hantzsch ester is used as a mild reducing agent for the reduction of trifluoromethanesulfonic anhydride activated amides providing the tertiary amines with high functional group tolerance.
متن کاملChemoselective Intermolecular Cross-Enolate-Type Coupling of Amides
A new approach for the synthesis of 1,4-dicarbonyl compounds is reported. Chemoselective activation of amide carbonyl functionality and subsequent umpolung via N-oxide addition generates an electrophilic enolonium species that can be coupled with a wide range of nucleophilic enolates. The method conveys broad functional group tolerance on both components, does not suffer from formation of homoc...
متن کاملAn efficient and chemoselective synthesis of N-substituted 2-aminopyridines via a microwave-assisted multicomponent reaction.
A facile and selective synthesis of N-substituted 2-aminopyridines is accomplished via microwave-assisted multi-component reactions controlled by the basicity of amine and the nature of solvent. In addition, a possible mechanism accounting for the reaction was proposed.

متن کاملChemoselective Reduction of Tertiary Amides under Thermal Control: Formation of either Aldehydes or Amines.
The chemoselective reduction of amides in the presence of other more reactive reducible functional groups is a highly challenging transformation, and successful examples thereof are most valuable in synthetic organic chemistry. Only a limited number of systems have demonstrated the chemoselective reduction of amides over ketones. Until now, the aldehyde functionality has not been shown to be co...
