Tosylmethylamines as “Nonstabilized” α-Aminocarbanion Synthon Equivalents: Advantages and Limitations
摘要:
Tosylmethylamines (1) are advantageous synthon equivalents for ''nonstabilized'' alpha-aminocarbanions of aromatic amines, Clean reactions and high yields are observed provided one-step procedures are utilized: the intermediate ''nonstabilized'' alpha-aminocarbanions are of low stability, Reactions formally involving dianions from bis(tosylmethyl)-substituted amines have also been achieved.
