Synthesis of Iminonitriles by Oxone/TBAB-Mediated One-Pot Oxidative Three-Component Strecker Reaction
摘要:
Oxidative three-component reaction of aldehydes, amines, and TMSCN in a biphasic solvent system (toluene/H2O) containing Oxone, tetra-n-butylammonium bromide (TBAB) and sodium bicarbonate afforded alpha-iminonitriles in good to excellent yields. This oxidative Strecker reaction was applicable to a wide range of aldehydes and amines, aromatic or aliphatic, of different electronic and steric properties. Substituted 1-aza-2-cyano-1,3-dienes were also accessible using alpha,beta-unsaturated aldehydes as inputs.

L-Proline (20 mol %) was found to be an efficient organocatalyst for one pot synthesis of a variety of alpha-aminonitriles from aldehydes, amines, and trimethylsilyl cyanide (TMSCN) in acetonitrile at ambient temperature giving good to excellent yields (72-95%).
