Dialkylaminoacetonitrile Derivatives as Amide Synthons. A One-Pot Preparation of Heteroaryl Amides via a Strategy of Sequential SNAr Substitution and Oxidation
摘要:
Dialkylamino acetonitrile derivatives were utilized as alternative to cyanohydrin synthons for preparation of the corresponding heteroaryl dialkyl amides via a strategy of sequential base-mediated coupling and oxidation. The most advantageous oxidant, NiO2-H2O, can readily oxidize 2-substituted aminoacetonitriles to the corresponding amides under both basic and neutral conditions by forming cyanohydrins in situ.

The pracitally unknown α-secondary allylamines 1 have been synthesised in good to very good yields by reaction of allylaminonitriles 7 with Grignard reagents. The reaction is regio- and stereoselective and can also be run with α-aminonitriles 9 and vinyl Grignard reagents.
